I think watch Topic capability here is a real kick-ass stuff. Can we extend it to "Watch Forum"? This would make us closely follow our favourite forums! This can probably have a e-mail when a new topic is posted in a forum. An e-mail for all the posts may become a spamming routine for busy forums! I dont know whether the bartenders have that feature enabled for them but it will really be helpful for them.
The feature doesn't exist for moderators, either. What's more, I'm fairly certain none of us would use it even if it did exist. We're all volunteers, and don't sit around waiting for posts to come in in order to moderate; rather, we do it at our leisure. For that, the existing forum pages (as well as Today's Active Topics page) work fine.
As Ben suggests, RSS is the modern-day method to keep tabs on a forum.
