Alright so here's the deal. As of right now (March 28 2009), I will be allowing members to change their Username to something else.
I will leave this offer up for the time being, but after a good enough time has pass, I will not be accepting any changes, except under special circumstances.
If you would like to request a name change, PM me with your given username, and the username you would like to change to.
Once again, this offer is limited, and will soon be closed off to all but members with large post counts total, and special circumstances. i.e. same name issues.
