Howdy from Texas! To find threads that you have started & threads that you have replied to you just click on your profile at the top of the page (My Profile) and there you will find a place to the far left of the screen under your board name that says "find latest posts" & "find latest started threads". Click on which ever one you are looking for & you will see your post there & you can click on it to read what you & others have said on that thread. Hope this helps you.
Have fun here & ask questions...someone is willing to come along & help.
