I was pretty sure that the 'We don't do name changes on request' thing was in reference to petitions. So like, that means don't petition it. I don't see anything wrong with posting a request in the forums, especially if there is a good reason for the change (such as: you know that your name violates policy and you are turning yourself in), or something like that.
But of course, I have absolutely no authority here, and similarly no knowledge of gm rules/policys/regulations/charters/mandates/and/or/guidelines (especially in regards to wiz), and am basically just talking to talk and throw in my two cents.
