I like the basic idea because it actually has a practical use. However, I am against people being able to select anything they want. IMHO, it would be wise to keep any invitations for "forum whores" to the minimum. We have pretty small avatars and signatures, and that's good the way it is. There are enough forums full of brain-damaged kiddies who need 3 animated gifs in their sig (250 pixels high, of course), a huge avatar and a flashy custom title like "His royal 1337ness" or crap like that. It would only invite people to play around with that stuff instead of focusing on what's important.
So my 2 cents is: Some pre-defined functional titles (Bot creator/coder, President, Council Member, Super Mod, Mod for forum xyz, PHP maintainer, waypointer
etc.) yes - free choice (and worse, flashy text formatting) for anyone, no. I don't like the "minimum post count" idea, either - sounds like just another invitation for forum whores to me.
But do what you want (bleh, as if you wouldn't do that anyway
) - I guess I won't cry and leave if the outcome of this poll differs from my opinion. Maybe the community here is even good (mature) enough to prevent any unpleasant side aspects from happening. 9_9
$eu_crey$$on, your avatar is hideous. I had to say that.
