I would like to buy a package and it sais I can reserve my username. I was wondering if this is the username of this site or can I choose one in - game?

The username on the forums is the same as the one that is used in game.

Darn it. Is there a way I can change it?

Not that I know of. I don’t know if @james can change it behind the scenes.

The other option would be just to create a new account.

At the moment there is no way to change your username.

Quite a few people have requested it - so it’s on the todo list - but not a high priority.

You can always create a new account - but you would need to switch out the email address you’re currently using. One technique is to use address tags.
