I might want a name change... I usually get mixed up with Brave_Dragon, Kanohi Dragon, and sometimes Bionicle Rex! However, I like my name mostly, so it's not too bad to get mixed up.
If I did change my name, I'd have to change everything in my comics, which has used my name regularly, and people might get confused about who I am. I'd have to change the title of the blog, and I'd probably end up with a cool name for a while.
Those are the pros and the cons for ya. Criticise if you want.
