I just installed an update that lets you set your display name for the forums. You can do this by logging into your control panel, and going to your user profile and filling out the display name field.
The link takes me to http://gamingoutpost.com/wp-admin ; I get a Word Press logo and the sentence, "You do not have sufficient permissions to access this page." I poked around in the Profile just in case there was another way to access the function, but if there is I didn't find it.
Hmm... That's strange. Did you create your account on this new site through the forums? I know I edited the code shortly after launch to force to you create an account through the /wp-admin/ part of the site, but if you did it before I made that change, that could be causing the problem. Let me know.
Yep, actually, that was the problem. I had to give you the right user permission setting, since creating your account in the forums gave the wrong one. You should be able to log in and change your display name now.
