Not sure if this is the correct forum for this, but here goes.
I've been using WP for a number of years, but am new to BuddyPress and WPMU. I want to create a site using WP as a CMS, but with advanced visitor interactivity. I want users to be able to post their own photos and videos to the site on blog posts and in an events section. Is this possible with WP? Or does this require a custom CMS solution?
