power auras classic type addon with announcements

[vlakarados]

actually, I'm looking even for a plugin to power auras, to announce in say/raid/party/rw chats customized messages, but nevertheless I couldn't find anything similar, what I would like to see is an addon that allows me to add buffs/debuffs by spell name/id and to announce custom messages in chat as I gain them or they fade. the only thing I found is NightWatch, but it's not really what would be perfect for me

can someone help me with that?
