I think it would be fun (although the logistics of it may be complicated) for the fans to vote for best tits, best ass, best smile etc etc. Could help spark sales based on fan interests.
Now, arguing with my own idea... I don't think it's always a good thing for women to be compared to one another. Sparking drama wouldn't be cool. But you guys may have ideas to shape this or other suggestions.
It would also be awesome to have a tagging system for the charms. That way visitors/potential fans could search by keywords.
I'm just trying to help out because I think the ladies here are awesome and I think the site deserves to be even bigger than it is
