I submitted some work to the "busts" gallery section a while ago, but they don't seem to be around yet. I waited for the suggested time span, but...
Did my stuff get shot down or is there just some kind of delay in the system?

You posted them the 14th, right? They're here. Or maybe I can see them because I'm a mod, I don't know... Try to click this: http://rpgrevolution.com/forums/uploads/13...86_202_2924.png. If it says you don't have permission, they need to be approved by an admin. Maybe a global mod can do it too, I don't know.
It was Holder who was in charge of the Gallery, so that would explain the delay.

EDIT: I can see them too as a guest. So if you uploaded a more recent one than tigra.png, well they're invisible and need approval.

They were accepted about two hours ago
