Just finished up a new feature. It's called 'MyThreads'. Here's how it works:
Let's say you reply to a thread. Then the next day, you come on and wonder if anyone has replied to that thread that you did yesterday. Problem is, you can't remember which thread it was!! Don't fret my young soldier, now all you have to do is visit your MyThreads section!
This section holds all active threads in which you have participated in. Then once you read them, they get taken off your list. If someone replies again, it goes back on, and so on.
I haven't put it in the menu yet, but until then, try it out and let me know what you think!
