Hope to see photo counts by user in a future release.
For our site, the number of photos posted in used to determine a discount for membership fees.
I added a field called 'photos' into the vb_user table, and hacked photopost to increment it (instead of pp_user).
Had a go at it in RC1, but got a little dazed and confused by the approval logic.
This field would also be used to generate a "Top Posters" block for cmps.
