One of our big goals at Telligent was to have our Community Server product be disruptive and change the way people work within communitites.
Community Server has a great forums solution, but I'm also now happy to announce our NNTP server. Yes, you can now connect to news://communityserver.org with Outlook Express. You can browse anonymously or you can login with the same credentials used at www.communityserver.org. Go ahead, give it a try...
