Re: Stupid me
If you go to your usercp and go to options, then go down to where it says "default thread subscription mode" click the dropdown box and select how often you want email notifications of your subscribed threads, or if you don't want that click on "no email notification". Then it will subscribe to every thread you post in and you can keep track of them on the main page of your usercp.
That is for the future, but if you want to see all the posts you've previously made, do what celegorm said and click on your name and go to your user profile and click "see all posts made by this user".
When all else fails...Ham Radio!
