I'm looking for a mod that, on receiving a whisper, whispers another character. Or executes a macro or such, on the event of a whisper. This would be for my dual-box situation, where one character is always following me and when a whisper is sent to my follower I'd like my active screen to be notified so I don't keep these people waiting too long or just generally come across as someone who just doesn't bother to respond
Thanks in advance.
(edit)
Cowbell PMed me with the following info earlier, and I noticed there is a mod for this:
WoWInterface Downloads : TwoBox Toolkit
It's called the two-box toolkit. Thanks Cowbell

I will try it out tonight.
