Also... it usually makes more sense to use the raidbot for... yeah, raiding, and the guildbot's privategroup as a guestchannel. That way you do not need to relay anything between the two bots. If you want them to use the same base tables, you can use table prefixes, or just copy everything over once per day or so.
I kinda fail to see the point in using a raidbot as guestchannel... just turn on the relay of the guildbot. Command is "!relay". If you are raiding heavily and cannot just turn off the relay to turn the privategroup into a raidchannel, that's the point when you need a second bot, a raidbot.
I think I repeated myself... sorry, deep in the night here.
