New to 3 boxing in wow but not boxing ;)

So i found Clone Keys for my macbook pro and this is the greatest thing since sliced bread... I now have 3 shaman up and running Vitamina,Vitaminb,Vitaminc on Maelstrom.. I did some macroin and got my addons setup for all the auto accept stuff .... and auto follow.. Does anyone know of an addon that will respond to /brb to make the rest of your party sit still until you get back ? cause I want to boost my shaman up with my 4th account 70 paladin.. but I want to be able to have them follow and then click /brb macro have them stay put then clear some mobs then do /followme... I could rig somethingup pretty easy i suppose but I figure to ask if first incase there is something in toolbox addon for this feature.

Regardless It should be a fun run to 70 on these shaman I love boxing and I hope the community of boxers here in wow is just as great as the boxing community in EQ.

First let me say Welcome and Gratz on muliboxing WOW.

As far as leaving my alts behind I just push the "pause key" and then go do my business then when I am ready I unpause the screens and get my toons. There my be many other ways to do this but that is simply what I do. It would be kewl to know what some of the more exsperenced players do .
