Never - on a site you may end up using seriously rather than just a fan art account - make your name/url (which cannot be changed without paying) something embarrassing/stupid/related to the fan art you used to do.
I made this mistake.
Now look at the mess I'm in.
Why on earth did I even call my deviantart onlyhopeformeismcr? Of course, I still love My Chemical Romance, but really? And now I can't even change it. Well done 2011 me. A*. You're an arsehole.
Anyway, I hope you're all doing well. I'm going to try doing more art since I've done nothing in the last month or so.
