For future reference . . . you can subscribe to a thread when you post in it . . . instead of using the quick reply box, click on the 'Advanced' button under that box and put your post in there. Before you click on the 'submit reply' button, scroll down a little on the page (scroll bar at the far right of the screen) and you will find a little section called 'thread subscription'. Click in there to see the options available; pick one; then do the 'submit reply' thing. Depending on which option you choose you will receive a noficiation each time there is a new entry to that thread. If you choose 'no notification' you can still find everything you subscribed to, by clicking on "User CP" in the main navigation bar at the very top of the forum (just under the picture of the 3 chickies).
Hope that helps.
