This might be a stupid question, but how do you change the "Adventurer is [x]" in the forums? I don't really know how to explain what it is, sorry if I'm being vague.

Assuming you're talking about the Titles (the things that show up around your username on the forums) - you can change those HERE! (:

Keep in mind that you need to earn various titles by completing certain achievements (or participating in site events that award titles) (:

Okay, thank you very much!
