I feel like you should have each name shown as former aliases (like steam does) so that people can tell who was who originally.

We've already planned this as an administrative feature, but it does make sense to expose this to other users, along with a date, like:

Cormyn's naming history:
Cormyn, January 10, 2011 to present
Kormyn, August 2, 2010 to January 10, 2011
Nymroc, April 17, 2010 to August 2, 2010
Cormyn, January 11, 2010 to April 17, 2010

Can you keep your username?

If you're asking "do we *have* to change our username?" then the answer is no. This is an opt-in service that we're going to build for users who want to change their username.

Well I've got the best new username, but I'm not going to say, because someone may steal it. All I will say is it has

Zero

in it somewhere. But not GhostOfZero ( I don't see the point of GhostOf in front of your name).

it does make sense to expose this to other users, along with a date, like:

If the user doesn't want to have their old username displayed, will there be a feature for them to hide it?

( I don't see the point of GhostOf in front of your name).

It's for a game.
A club thing for Exit Path, now that it's over I'm going to change my username as soon as the feature is available on AG3.

I have an important question about usernames. When you change your username, do your points magically disappear just like your username?

And also, how did Cormyn change his username? He said it was only available in AG3.

Why can't you just change it? why does it have to have this huge fiasco behind it? You should be able to change your username in th user's settings with no huge process or naming history.. etc. basically, quit being babies

They aren't being babies, they just haven't put in the feature yet. If they hadn't even talked about it, and you hadn't known about it, you wouldn't be calling them babies.

They're making it a huge deal when there doesn't need to be...
you have to be a good person in AG and no one else can steal your username for 30 days wha wha wha...
Just have it as an option to change your username. Like I had mine when I was what... 16? I thought it was cool, but now my username is kind of dumb. Instead of it being this huge process, just lemme change the thing.

Its just that they didn't think of the idea to put that in before.

And also, how did Cormyn change his username?

He didn't. That was an example.
And the reason we need to be a "good person" and a ll that is because the ability to change it is a privilege, not a right.
