okay, I'm not trying to complain here, but doesn't having 2 titles seem a little reduntant?

I was doing my thinking along the lines of a hack that would make the text field and radio buttons that exit in the CP viewable for those with over a predetemined number of posts.
That would let people set their custom title.

The only thing I would add to that is a CP per user permission so you can turn off abusive users while letting the good ones have one.

Just my thoughts...
