Convenient user upgrades...

[MrSun]

It would be nice to rate topics (like in the old nabble forums) and have custom icons for your topic to set a mood.

Most people complained about ratings on old Nabble, so we removed them.  I personally like ratings.  We will eventually open up Nabble and allow anyone to add features including ratings and small things the topic custom icons you want.  But that is several months away.
