whisper for battleground popup

Hello, I did some boxing a few years ago and although Im just single boxing now, I still read those forums to learn more about the game. In the past, I was using a voice boxing program (I forgot the name) then keyclone and twobox toolkit.

My question is the following : I still have different accounts. And the time to join a battleground is quite high on my server. About 15 to 20 minutes. I would like to farm on one character while Im waiting for BG on my main (who is not a farmer). Both would be on "full screen windowed" mode and I would like to receive a message or a whisper informing my farming alt that the main has received the message to enter the battleground.

So, I don't know if Jamba or another addon does that. It's not really for dual-boxing as I just need the information for the BG proc. Of course, if both characters are 85, I can put them together in a team waiting for the BG but I would like to get the message while I'm levelling some low level alts.

Thanks very much for your help !!!

Along the same lines ... anyone know if there's an addon that will send a whisper/alert to another toon when the Tol Barad queue pops? There are countless times when I've gotten 2-3 of my 5 toons into Tol Barad and while battling, I miss the queue pops for the remaining toons and I have to re-queue them. It would really help if I could find a way for the queue pop to alert me on another toon.

Don't want to be impolite but a little and last bump hoping for a solution if it exists.
Thanks!
