It'd be really nice if every time a player or the GM posted in the campaign forum, all the players/GMs got an email letting them know, just like how I get an email now if someone comments on my site. This seems like it'd be really easy to implement, and it'd really help in getting the players involved in the site. Right now, I'm paying for a premium membership, but my forum is probably going to be pretty barren since there's no notification to my players when someone posts.

Please correct me if that isn't what you are asking for.
