Something I dont see very often, and a feature I really like about his forum, is that when you are posting a new message, if someone else posts before you, then are notified.
I think it would also be nice, if when you modified your message, if a new post was made, then you would get the same message. Sometimes I modify my message, only to notice that the reason I modified it, has already been addressed by another member, so there ends up being a repeat.
Just a small thing, but something I thought would be useful.
