I’m unable to create a cgportfolio, and I’m guessing this is because of the hyphens in my username. I’ve checked the FAQ, and it tells me that i can select domain when i create the portfolio or something, but i just get “file missing” when i try the creation link, and if i try the domain matching my username I just get the standard portfolio frontpage. And as far as i can see, there is no way to change my forum username.
I’m i just stupid, am i doing it wrong? 
Is a admin able to change it for me, or do i have to delete my 10 year old user and create a new?
