When you connect, indicate you want membership change messages. Every
time you receive one, you'll have the current "user" list for a group.
You get one when you join a group to form your initial list.
AFAIK, there is no way to query the group for membership directly. You
have to indicate you want membership change messages *per connection*,
not per group.
specifically the "If This is a MEMB_MESSAGE ..." section.
