what about a section posting links? probably couldn't do pictures in that case because of bandwith, but a special section for people to post specific videos and comment on them wouldn't take much more bandwidth.
when we have big threads of vids they always turn into "Who can post video of the dumbest person shooting!" This way we could ban everyone(or just lock the thread) who posts a video of middle-eastern men shooting a .577 t-rex, or a heavy-set man shooting an encore.
keep it to high-roaders posting themselves out shooting, instructional videos, or just their youtube favorites.
