I am also thinking of writing an addon. I was going to add a few things to it, and more as I saw fit. So far my list of 'stuff' consists of:
  • Broadcast emotes
  • Say a random sentence/emote (this would be on all the time, probably once every 10 minutes or so one of the toons would so something random)
  • Broadcast speach (something like '/mb guild huhuhuhuhu' would make all the toons say 'huhuhuhuhu' to the guild or whatever variable is set)
  • Whisper alerts, whenever a whisper is sent to a 'follow toon' the whisper would be forwarded with the senders name
That's all I can think of atm. =P
