Hi Chan,

Groups and membership in Spread are created dynamically on the fly in 
response to client requests.  When a client calls SP_join() on some group 
name, if the group does not already exist, then it is created at that time 
upon demand.  If the group already exists (i.e. - other clients have 
already SP_join()'ed into that group), then the new member is added to the 
group and a membership change message is delivered to all the current 
members.  Similarly, if a client is in a group and then either SP_leave()s 
or disconnects then the members will recieve a membership change message 
that removes that client from the group.  When the last member either 
SP_leave()s or disconnects from Spread, then the group ceases to exist.
