Suck down a Cheesesteak for me while you're in Philly, eh?
I have two things that have come to mind as of late that would be nice additions when time permits. First, another site that I've seen uses an "activity meter" to help you sort between users who are regularly on and updating their portfolios, and those who came, posted, and then disappeared. At this point, of course, everyone sho is on the site is active, but a year from now I can see real value in this feature. Build it into the sort criteria and it becomes a great way to screen out those who are not as serious about the craft.
Second, I always liked being able to see a model's size information. I have no natural eye for this kind of stuff, and sometimes it helps to put a model's overrall physical presence into perspective. It also is a great way to make sure that the stuff that you bring will fit them (if you're dumb and forget to ask).
Again, not rush stuff by any means, just random thoughts.
My goal in life is to rid the world of ignorance...mainly my own.
