Thanks in advance for help.

There's a great tutorial thread by shorena, explaining signed messages, aswell as how to sign and verify them using different wallets / tools, in this very section.
Here's the section for blockchain.info, if that's what you're searching for.

Thanks in advance for help.

In your wallet copy the address you want to sign then go to File and click Sign Message.

Enter the  message you want to sign using that address and click Sign Message in the popup.

Hello,

When I'm in my wallet there is no file so when I did a Google search on topic I got following:

https://blockchain.info/tags?filter=16

Now do I enter my addy and where do I add other person's addy who I am verifying I am owner of account?

Thanks

Are you trying to sign a message from a desktop wallet or a blockchain.info web wallet?

It is better to make a new post with new information than to go back and edit a previously made post as the edit is often missed.

My edit actually was more regarding the formating of my post, not the content/links, those were there from the beginning.

I saw it and did it but after signing it I get signature code and don't know how to share it to verify.

How do I share this code, I don't have app showed in tutorial?

Thanks

You can copy the signed message and send it to whoever was wanting it. It would be up to them to verify the message.

[Lutpin]

The commonly used format would be the following:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
[insert your message here]
-----BEGIN SIGNATURE-----
[your bitcoin address]
[the signature blockchain.info provided]
-----END BITCOIN SIGNED MESSAGE-----

An example shorena made is this:

-----BEGIN BITCOIN SIGNED MESSAGE-----
This is shorena from bitcointalk.org and today is 2015.03.14
or as some of you might write it 03/14/15 pi day 2015
-----BEGIN SIGNATURE-----

IFtLgDZCpvfw0DT70RCLcYXj3Dbjf68sc6pj/C+u5K6IC8PIhHE4Y/ldllt1/yhrZpVW/shFRf7rxQYdsW/CcBM=
-----END BITCOIN SIGNED MESSAGE-----

The important part is, that you provide the other party with a) the message you signed, b) your bitcoin address and c) the signature.
All those three parts are needed to verify a signed message.

To verify the bitcoin signed message there are many websites, for example a good tool is this one and here too.

Thanks for not suggesting coinig. No one should use that broken tool.

To verify the bitcoin signed message there are many websites, for example a good tool is this one : https://tools.bitcoin.com/verifier.html and here too: https://www.blocktrail.com/BTC?verifysignedmessage=1

Just curious if OP falls into this category in the rules?

4. No referral code spam

Has a affiliate link in his profile,so was curious if this is kosher. Looks like signature was removed for same reason.

Posting referral code is not allowed, but having the refferal link/code in the profile is allowed as far as i know.

Yeah, pretty much this. If you include a ref link in your posts, there's a high chance it gets deleted.
But in signatures and profile information, it's allowed.
As for why the link in their sig was removed, that's the signature restriction for newbies, no links allowed.

Perhaps the allowed signature styling should change with activity score / membergroup. Like:
- Newbie: No styling (including links) allowed. Max 40 characters.
- Jr. Member: Links allowed. Max 100 characters.

Thank you all for your help, I got it.

The verifying site link that was posted allowed me try it myself before passing info to other and it stated it was verified so all set.

Thanks for taking time to help me with this, I greatly appreciate it all.

Don't worry, you are welcome, this remembers me my first steps in the bitcoin world, learning the basic things.

Wait, what is the benefit of signing a message?
What do we do with that?

I see they are using it when they are buying or selling in market.
How does that work? I mean what if i dont sign a message?
Is this to prove that i own the address or what?
Sorry if my post is not related to OP .

Signing a message proves that you own the address. If someone knows that you own an address, when they receive a signed message from your address, they can be sure that that message did in fact come from you. With accounts here, signing a message from a previously posted address means that there is a very high chance that the person who posted the address is also the same person as the one who controls the account.
