got groups and forums to connect to each other -- either one-way or two-way, with multiple links in either direction. Sounds complicated but it's not -- I'll write a wiki page.

Basically admins can link groups and forums so that your posts to each are automatically crossposted to any related areas for maximum visibility.

I also added regular group-to-group crossposting that anybody can use, by clicking the "Share" button on any post.
