This script takes !recall to another level. Rather than making a copy for every channel, it autodetects a message in a channel, and sets that channel as a "slot". There are 10 available, and this can easily be expanded. After being set in a slot and at least 5 things are said, users will be able to !recall, and get the last 5 messages for that channel. Please note, this is intended to be loaded into an mIRC bot, not a user. You can run it off yourself, but you can't use it then. If you have any problems with this script, comment below, or email me at DiddyPZC@gmail.com.
