Hey I thought about, why you havn't made a notification thing for your topics.
So that you get a notification every time you have gotten a reply to one of your topics. instead of the fact you have to trace your topics, and view it every once in a while to see if somebody has replied to it.
Just a thought, I honestly don't have a clue about how to make it, but I'm sure someone does.
Might be too much work in it though, what do I know

Just wanted to post it up.
Have a nice day guys.
