In general people contacting our support desk are very polite and if our response fixes the problem, they reply with a "Thank you" email.Normally I close / resolve tickets when I reply with a solution which normally works, but this means the ones who send a thank you open the tickets again, making the stats for re-opened tickets high.What I would like to do is answer the tickets leaving them open and then have them automatically close after a couple of days if there is not a reply.
