Nice use of my Avatar Upload plugin! I see you’ve modded it a bit too by adding a classname to the image link, which is great.
I like the “Random Members” on the front page. I wonder if you’d consider sharing code, with full credit of course, so the random image thing can be added to the avatar upload plugin?
I don’t know how you’ve set-up your random script, but I can see it being made configurable, so users can select the number to display and if they wish to limit it to only people who have uploaded an avatar.
