[Spread-users] simplified code to illustrate groups problem I'm having

[John Schultz]

A "group message," as you are calling it, is a MEMBERSHIP message that 
tells you the current membership of the group.

These messages are generated by Spread, not users, and are only delivered 
when the membership of a group changes.  The first message you get is a 
group message telling you (and any other group members) that you've joined 
the group.

The other messages you get are the ones you sent to the group being 
delivered back to you.  These are regular messages, not membership 
messages.

Cheers!
