You can if you wish receive an email or an alert whenever someone posts in a particular forum. You could use it so you never mist a post in a forum that has a special interest to you. Here for example I'll show you how to watch the Belly Locker forum. Posts here don't appear on the recents page so it serves as a handy reminder that people are posting there.
Heres how to do it.
Navigate to the forum you want to watch
CLICK ON WATCH FORUM
Choose what you want to be alerted about. New Threads, new posts, etc and how you want to be alerted. Email or within the forum (best option)
You'll get your alerts and never miss a post in that particular forum again.
