Would it make sense to add a QR code with a bitcoin address for receiving change?

Currently using the bill to replace cash means that you either need to have the exact amount or else cash would be needed as well to supplement the payment amount or cash would need to be given as change.  With an exchange that floates, prices are probably not known until payment is made so the chances the buyer already has a paper bitcoin in the exact amount would be even more less-likely to occur.

If instead the paper bitcoin also had an address for receiving change, then the buyer could just carry a paper bitcoin(s) totaling at least the purchase price.

I see there is enough room in one of the unused corners for another QR code where the bitcoin address for the change could go.

The receiving address could even be a specially marked paper bitcoin, meant primarily for receiving change but could also be used for spending

Ughh ... this just makes the paper bitcoin even more complicated and not less so.

After you posted that message the twitter account @BTCrow posted:

Are you still running the service?

Easiest (and cheapest) ... if you are not in a hurry.

Mt. Gox -> Dwolla -> Bank -> PayPal
(assumes you are in the U.S.)

Otherwise, you can try trading with a seller on the #bitcoin-otc marketplace:

 - http://bitcoin-otc.com/
 - http://webchat.freenode.net/?channels=#bitcoin-otc-foyer

Because you would be receiving PayPal, a payment methods that can be reversed, you will want to make sure to only accept payment from a source that you trust.  The #bitcoin-otc marketplace's Web of Trust (WoT) can help to assure that you are trading with someone who has a good trust reputation and history.

Just out of curiousity, are you U.S. living in Canada?  If not, how does this impact you?

You could also try sending PMs to mcjeep, Oace, and jpapabreeze -- all of which expressed interest in buying:

 - https://bitcointalk.org/index.php?topic=39750.0

(and/or maybe post in those threads a link to this thread with a message that you are offering to sell.)

You might want to list a specific offer on the #Bitcoin-otc marketplace. Here the order book shows the variety of items bought and sold for bitcoins:
 - http://bitcoin-otc.com/vieworderbook.php

 - http://bitcoin-otc.com
 - http://webchat.freenode.net/?channels=#bitcoin-otc-foyer


There is also a classifieds site you could try listing your offer in:
 - http://www.bitcointrading.com

Good overall though some of the details were either outdated or incorrect.  It's a hard task because the project and its ecosystem is evolving so quickly.  Even the wiki is starting to show a number of areas needing update -- (e.g., wallet security article).

The wiki has two additional articles:
 - http://en.bitcoin.it/wiki/How_bitcoin_works
 - https://en.bitcoin.it/wiki/Introduction

Also, Bitcoin Primer: http://coinlab.com/2011/12/bitcoin-primer

And podcast (though over a year old now): http://www.bitcoinmoney.com/post/2560941112

There is some good stuff here:

The exchanges do already perform steps such as requiring verification for certain accounts, due to government regulations.


The message is not necessary for Bitcoin to be used as a currency.  Adding that would bloat the blockchain.

P2Pool is now about 60 GHash/s.   How will those appear in the chart?

Heh, and open source: https://github.com/spaculator/spaculator

Odd that he doesn't mention that in two weeks they'll be killing their online payments capability that Lauren (host) was asking about.

Well, having those funds in Dwolla exposes Mt. Gox to risk.  Though Mt. Gox claimed to have an arrangement with Dwolla where Dwolla would not  reverse transactions, that doesn't mean Dwolla doesn't have the ability to do so (and has already done so with other exchanges).  Also keep in mind that it is entirely possible that an e-gold moment could happen where funds get frozen not by Dwolla but by a regulator instead since funds held at Dwolla are kept with an FDIC- or NCUA-insured bank.

Since Gox can add funds to Dwolla within a business day or two, this current cash management practice shouldn't be the end of the world.

The help page doesn't describe what happens if there is a dispute:

Heh, just hope they don't first do a $1 (or some other smallish amount) transaction (for getting auth only) first and then attempt to do the $25 as a separate transaction (which will then get denied as the total available would then be less than $25).

They being the bank or they being GetBitcoin?

Needs a support service, like UserVoice or something.   Maybe OSQA (Python, open source)?

So that this thread doesn't get the minutia, such as this:
