Hey Chad,its pretty simple,on the upper left of the screen go to "user cp,once there go to "subscribed threads" to see all threads you've posted in,if i want to watch a thread or follow a issue that interests me in a thread that i dont have anything to add, i just insert a smiley face,that way the thread will be in my "subscribed threads".
You can also select ways to use Audioholics from your user cp,you can set the subscribed threads to show your threads to you in a number of different ways,including the time period in which to store your threads,you can also adjust the way you see all threads in the number of posts per page,i set mine to 40 posts per page.
Hope this helps.
