Maybe I'm having a senior moment, but Digi's do not have anything to do with group message codes.  APRS "Message groups" are just aliases that your own station will trap as if it was a message to you.  Messages can only get to you from local RF since the IGate does not know what your groups are... Thought on the APRS-IS, I guess you can get them from anywhere...

Oh, I see, a blanket forwarding to RF of all messages addressed to "NS"..?

Rightly so...

Another way to handle group messaging is via AA5PL's CQSRVR.  Everyone that wants to participate can send a CQ NS message to the CQSRVR and will stay on the list for 24 h ours...
