I have a suggestion. Is there someway you could add something to let us know if we have posted in a thread. Many times I have seen a thread and can't remember if I have posted in it. It would be nice to have some sign to show that you are an active poster in a thread.
I have been on other sites (wont mention the name) where the thread name will change color if you have posted in it. I found this to be very helpful keeping track of various discussions.
