Ah yeah. I've been pushing to get that opened up for everyone but still have yet to receive a response unfortunately. I'll keep you updated though if you'd like!
Haha, everyone's thinking the same thing with premium perks xD
You have nothing to apologize for! It's all good~ I was really intimidated when I joined as well, and it took so long until I got to know enough people to open up. The hardcore community really scared me back then.
I'm always here if you want to chat, on the forums or on the IRC webchat :3
Profile customization is, for some reason that escapes me, unfortunately currently only available to staff. We've been working on opening it up to the members since they're the ones who actually want to use it, but so far no response.
Or if perhaps you are referring to personal profile info, you can edit that in the User CP. The title beneath your username however, is preset until you reach premium (1000 posts). Once you do so, you can change it to whatever you like.
