Timer or Clock option on IN SEARCH OF/ISO forums

I started this thread on the Dallas Forum just to see what kind of feedback I saw. Nothing negative, so I thiught I would ask here.

So often, ISO post have a deadline by the poster. Sometimes that deadline is withing an hour or two, sometimes it may be a week or two.

I know that Polls have the ability to expire or close, would be nice if members had an option to have their ISOs close sometimes. That would stop the replies to an ISO 3 days after the guy's needs had been met.
