I see that some people have changed their screenname since I've been here. How do you do do this?

My Account > Account Settings, the option should be there.

Under account settings, not sure where because it doesn't show up if you have changed your name within the last 6 months, which i have done, and you can only change it once every 6 months

Aah thanks. I figured it would have been in the control panel or something.

This can be closed since your question has been answered. HS/admin; I forgot I don't have power here. xD
