First: A button on the toolbar, next to the "create new project" button, and the "search" button, should be a "View the Forum" or "Forum" button. Such a thing could come in handy and encourage people to communicate via the topics.
Second: A way to find authors, and perhaps, a "last online on: 0:00 0/0/00" on someones profile, to be able to tell if they are active participants of the site currently. If they are online it could just say "online now". How am I supposed to meet new people if I can't find anybody who will realize I've contacted them?
Third: an "all recent activity" and a "who's online" option on your homepage, to see who's active, once more. That would be helpful.
