can we get a little check?

on some messageboards you can enable a feature that shows a check or unbolds the TOPIC if you've visited/posted in that topic. is this at all possible? <!--EZCODE EMOTICON START :shrug --><img src=http://www.sahoops.net/smilies/shrug.gif ALT=":shrug"><!--EZCODE EMOTICON END--> <p></p><i></i>

Usually when I've finished reading everything I click on the "mark forum read" thing...I don't know if there's anything else that can be done... <p><!--EZCODE CENTER START--><div style="text-align:center"><br>
