glad you have it figured out -
I don't know of much documentation on message channels. Might be some in 
confluence but nothing that I know of specifically on it. I just know 
the format for announcements in general
and that the motd (announcement tool configured to the motd channel) is 
treated specially by the motd tool itself. I guess the way you verify it 
works is to hook it up and try it out - but I think you have it now.
