What I've found difficult is keeping track of the forums I make/reply to. I think it would be VERY handy if there were a message sent to you letting you know that someone posted on your forum, like it does with comments and games. And another thing would be if you were able to “track” other topics and then get a similar message if your “tracked” topic had a new post.

Well, one solution right now is to use the RSS next to the topic title.

But I think this forum doesn't support notifications, so it'd probably take a lot of work to edit it so.
