Have you thought about an email notification system that notifies the person posting when another person replies to the post? This could be a simple check box that tells the system to send you an email everytime someone posts a reply to a thread to which you have posted.
Basically it is a "track this thread" notification. Most people will not have time to monitor the entire site by clicking on the "posts you have not read" shortcut. But if there was a shortcut to review "posts to threads you have posted to" and "posts to threads that you are montoring" (whether you have posted to them or not) would be helpful.
But ulimately, I would like to "opt" in for email notification so I don't have to keep comming back to check the site.
