Two small additions I'd like to see.

"My Threads" will only work if you have your subscription settings set to automatically subscribe to threads, which up until now has not been the default although I just changed it to that for new members going forward. You can edit that setting here: https://www.talkemount.com/profile.php?do=editoptions

Setting "Default Thread Subscription Mode" to "Through my control panel only" should do the trick. From that point on, you will be "subscribed" to threads which you participate in. Then to view your threads, click on "Quick Links" at the top and choose "Subscribed Threads" from the drop down menu.
