Create A Forum - Support Forums

Any time I try it tells me that my username doesn't exist. I tried registering and it told me the username wasn't available...I made the forum I'm supposed to be the admin I guess, but I can't get onto the dang thing...my forum is http://yugiohrp.createaforum.com/index.php

also, if you signed up with a name and then changed the display name, you still have to sign in using the original name, not the amended display name. ie. I signed up using my name, Richard, but changed the 'Display' name to 'Admin' yet I still have to sign in using Richard
