I am new to this site, and thus far I have found it very interesting, and I plan to stay.
I think it would be helpful if there was a button that allowed users to see a list of all of the topics they have replied to, in descending order from the one with the most recent activity.
There are loads of other forums out on the web, and the easiest ones to navigate have this feature. It's very helpful because, even on a board with a variety of subforums, it makes it easy to keep track of your posts.
It can be very frustrating to search through nine subforums for a post that you replied to, not knowing exactly which one it is in.
It's just an idea, I'm sorry if it's not clear. I'm having a little bit of difficulty explaining what I mean. I just think it would make for an easier, more enjoyable forum experience.
