easiest way to keep track of your posts is to go to User CP, then Edit Options, and make sure that "Default Thread Subscription Mode" is set to something other than "Do Not Subscribe". i make sure mine is set to "no email notification". then all you need to do is click on User CP and you'll all the thread's you've posted in that have new posts. if you want to see an older thread, just click on "View all subscribed threads".
