Due to xat's continuous problems we're getting rid of that in favor of something I found called chatango. Simply join the chat, located at the bottom of the forum, and then click set your name. Then you can choose a temporary name, or, register so then people can pm you from there as well and have a customized name.
A lot of us liked xat yes, but, there's just been too much wrong with it lately for us to want to keep having it as a main chat source for the site. We hope you guys understand and look forward to seeing you in the chat.
