here's an idea - when you have a problem, and it becomes fixed, POST THE SOLUTION
this is a help board where people seeking help are first asked to search for a similar problem and see if it has a solution. If everyone just emptied their posts when solved, what kind of knowledgebase would that create??? 'nm'???
oh, and click on the 'mark thread resolved' link at the bottom to show that a thread has been solved.
