You guys should find a good bulletin board script and integrate it with the mediashare. I would definitely get a lot of use from something like that and It would increase SEO as well.
I hear phpBB is pretty good, but I trust your judgement.
Ive been working with Mediashare and so far so good. Its very workable, and I like how you seperated the images page from the videos page for individual customization.
Its a little consuming at first but im getting pretty familiarized with the layout.
I would like to add a bulletin section to my site but my php knowledge is just good enough to limp me through each project.
