Why not link them all to the forums?
For example if you sign up at the forums you are also signed up at everywhere else. There could be a new counter that tells how many quest in the qdb
Example:
Post:2014
Quest:8
So why not? It would make usernames much eaiser to handle. It looked werid at the qdb when a mid/oldbie had a different username then there forum name.
What do you think?
