The community demand for username changes is obvious, but the mods claim this is a big decision to make and so we must wait.
One mod posted this before locking it:
There's really no point in everyone continuing to post here just to say they want a name change. We're still in the process of trying to get the forums sorted out and functioning properly, so allowing name changes are not very high on the priority list at the moment. Yes, it's a simple thing to do in the admin panel, but it is a decision that needs to be thought out before it happens, otherwise people are just going to go overboard with it. Just be patient.
Preventing people from going overboard is very simple: limit it to one change every certain number of years, and only to accounts over certain ages.
Personally, I've wanted to change my own username for years. I've talked to the admins about this before several times and they claimed wasn't possible with the old forum software. Well now it definitely is possible, and it's about time that we were allowed to do it.
