11) Perhaps after the performance/security updates are reasonable, have you guys thinked about a more user-friendly outlook with nice buttons, and theme, to make this wallet more user friendly.
Sure they have but it's created by volunteers and they are developers not designers. Perhaps if you have UI design skills you can contribute to this open source project? The git repo is at https://github.com/spesmilo/electrum/

As stated from the title, are already aviable others wallet implementations that share the same seed wordlist and use the same path/derivation of electrum?
Electrum is software. It is on github. It is on lots of peoples hard drives. If you are worried about all that disappearing make your own copy of it.

switch to a different electrum server. electrum servers are run by volunteers and sometimes the servers can go down. so just switch to a different server. I'm not familiar with the android version or I'd tell you how to switch to a different server. Look in network preferences if something like that exists in the android version.

"IMO it is better to install it from the electrum website where you can get the latest version."
My problem with this is that it does not integrate Electrum into the Debian shell handlers, so that 1) the program does not update automatically when new versions are released, and 2) it cannot be removed [program and user files] if a problem arises and that's necessary.
The jesse PPA is woefully outdated (version 1.9.8-4) and with noted problems, as well.
Ubuntu and other Debian variants of Linux are by far its most ubiquitous platforms. It seems to me they deserve an install/update mechanism that fully works for them.
Please read the third paragraph of my post above as well. Updating is easy with pip. Unless someone volunteers to maintain a newer version of electrum for ubuntu or debian installing from the electrum website is the best way forward IMO. Debian repos are not ppa. Those are personal package archives created by ubuntu users for that distro. They may or may not be trustworthy. Debian repos are maintained by debian developers and thoroughly tested by users around the world. As a result they tend to be older versions because all that takes time.

So did this change or is this about semantics, like these words are named another way or brainwallet is specificially something different?
It's about semantics. When people say brain wallet they usually mean something that they came up with that is a series of words that are human generated. Electrum mnemonic is computer generated and random so it is safe. Human generated words are not random so they are unsafe. Brain wallet is a confusing term so better to call it a mnemonic or seed rather than a brain wallet. I usually point people to this excellent rant by G Maxwell https://bitcointalk.org/index.php?topic=311000.msg3345309#msg3345309He mentions electrum mnemonics in the last paragraph. (oh and BTW years ago electrum allowed you to create your own mnemonic i.e. a brain wallet but it's no longer permitted. we may still be able to help you recover your old brain wallet. create a separate thread about it and mention when you created the wallet and what version of electrum you used)

What is your xpub key? This is your master public key in electrum.
If you share it publicly then your money will not be at risk, however anyone looking at this thread will effectively have a list of all your addresses in your electrum wallet.
This is like asking someone to make his bank statement public. You don't do that and no one should have to reveal his financial info publicly. in front of the amount text box , a label with the maximum balance amount which also can be clicked in order to set the amount text box to the value of max balance.
There is a way to do that although it isn't communicated well so most people don't know about it. You focus on the amount field by clicking on it and then press the exclamation point key on your keyboard to fill it with the max amount you can spend (excluding frozen addresses).

Using your operating system's command line (shell/command prompt NOT electrum console) you can do and electrum help <command_name> to get command specific help. For example electrum help listaddresses

You'll find 1.9.8 in the debian jessie repos: https://packages.debian.org/jessie/electrumIMO it is better to install it from the electrum website where you can get the latest version. Installing and updating is easy with python pip. You don't necessarily have to update each time a new version comes out. Only if there is a critical bug or you need a new feature that has just been introduced.

This has come up before. Electrum isn't designed to handle so many addresses. You should create a new wallet (file > new/restore) and send your bitcoins to an address in it. You can leave the old wallet file on your hard drive in case someone sends bitcoins to an address in it in the future.
To open a specific wallet file use file> open or the command line switch -w.

The developers have taken a program that was stable and turned it into a very unstable program that crashes all the time.
Bitcoin Core NEVER crashed on me until I installed 0.10.+, now I've had dozens of crashes. Once again it's crashed so hard I probably have to rebuild the blockchain... which is a waste of time since it will crash again.
Time for new developers, whoever was involved in making this is hurting the community.
It's usually the hardware in situations like these. I think your HDD has bad sectors/blocks. You should do a deep scan of it.

File > open.
You can make a shortcut like this:
electrum.exe -w c:\path\to\wallet\file

My question is, if someone gets a hold of my wallet for whatever reason, how easy is it for them to brute force it?
I believe it's not really designed to withstand brute forcing from an attacker. Just a single pass of AES 256. Bitcoin core, for example, does a variable number of passes depending on how much CPU power you have.

Doesn't this reduce the entropy of the seed?
Yes, but they compensate those lost entropy bits with other further bits of entropy How do you mean?

Can someone tell me what is the receiving address i should give a site when they ask for my bitcoin address to receive btc in the future?
On 2.x you can choose any address from the addresses tab. On 1.9.x it's the receiving tab. These are all your addresses. So i could have 10btc at one address and 5 btc in another address in electrum? Or its best to keep it all in one address?
Using a different address per transaction is recommended for privacy reasons. But you can reuse addresses. Addresses don't stop working just because you've used them in the past. There is no advantage to consolidating all bitcoins in one address.

To determine if a mnemonic is valid without using a word list, Electrum 2.x takes an HMAC of it (using a hardcoded key) and looks at the first byte. In pseudocode: if hmac_sha512(key="Seed version", utf8_encoded_mnemonic_sentence)[0] ≠ 0x01: fail("invalid checksum")
The only way Electrum can create a mnemonic whose first byte of HMAC is the byte 0x01 is by generating different mnemonics and trying each's HMAC until it finds a valid one, similar to the way vanity address generators work. Doesn't this reduce the entropy of the seed? If you are going to discard the majority of them and only use the one's that have a mnemonic with a hash beginning with 01 then that reduces the pool of all possible seeds.

Hi Guys I am getting started in Bitcoin and have a few questions. Is Electrum a good choice of Bitcoin wallet? I want something that has good usability. Can Electrum be trusted fully? The reason I ask is because the Windows Installer is signed by someone called Animazing. That is using a nickname rather than a real name, so how do I know they can be trusted? How do I check the PGP signature of the Windows Installer download? I believe I need the public PGP key of Animazing? Is this given on this page? http://bitcoin-otc.com/viewgpg.php?nick=AnimazingThanks You will have to read up on the person's reputation. The chief developer is Thomas Voegtlin (ThomasV) formerly of INRIA. Animazing is another contributor and he signs the Windows releases. If you know python you can go through the code. This way you are not trusting anyone. The devs' public keys can be found on the git repo: https://github.com/spesmilo/electrum/tree/master/pubkeysQuestions about electrum are best asked in the electrum forum: https://bitcointalk.org/index.php?board=98.0

My husband passed away last June and I'm unable to log into his wallet. I have not come across the seed nor the password for the wallet. Is there a way that I can get in touch with Electrum to access his wallet and reset info? Any information would be helpful.
Electrum is software installed on a computer. It is not an organization with information about your husband's or any one else's wallets. If you have neither the seed nor the password there isn't much that we can do. Even the wallet recovery people need some idea of what the password is before they can attempt a bruteforce of the wallet encryption. You should search for the seed. He may have written it down somewhere. It consists of 12-13 random English words.

I'm basically looking for a way to make electrum seeds without having to trust a computer. I'm worried that my copy of electrum could be compromised and only generate predictable seeds.
If your computer is compromised then it doesn't really matter how you generate a seed. Mal-electrum could simply send the seed to the hacker after you've created a wallet with it. I suggest shuffling a deck of cards and then making a string out of the result. Say some thing like 1s-2c-ad for 1 of spades, 2 of clubs, ace of diamonds etc. for the whole deck Then do an md5sum of that and restore your wallet using the resulting hex digits: echo -n "1s-2c-ad..."|md5sum
This will create non-bip32 wallet but it can be done on electrum 2.x because it is backward compatible with 1.9.8 wallets.
