Am I the only one who thinks it's fine the way it is?
Theymos said the forum doesn't need money, so paying a small fee doesn't help anyone. Theymos needs to spend time on this, and lately he's granted a few wishes for name changes. Great! Let's leave it at that.
Nah, I share the same opinion. It would also result in more work for theymos if he had to code the system to present users with a unique address, and then its the logistics of verifying that data. Ultimately, it would result in a lot more work for theymos which isn't necessarily a in demand request, and when the forum isn't in need of money it wouldn't be worth that additional time spent on this.
