+1 !
Just a thought, being able to pick out of a small selection of custom icons if you pay for a years worth of premium or something. Kind of like how Art Fight works.
Obviously no crowns, since those seem to be moderator/admin symbols.
Perhaps even just a small list you can choose from, like a Heart, a Rocket Ship, etc.
+1 I'd be more likely to keep my premium sub for longer periods of time if I got fancy flair to go with it (the star icon aside)
