Jamba, which is a multiboxer tool, does this. It doesn't say anything cool, but it swiftly dispatches the duel spammer. It also Taxi's all your toons to the same area, has your toons follow after combat, has them follow the masters selections while questing, repair gear automatically, sell junk automatically, buy specific items automatically... + more. Its well put together by Jafula, one of our forum members, so you can get support right here.
