I'm not sure how extensive it is. However, if you go to your User PC link on the top. You will see on the left hand menu (near the bottom), a link for "List subscriptions' under 'Subscribed Threads'. This has a list of thread you've posted in. However, again, I'm not sure how extensive this list is or how far back it goes.
