Yes, you right, I am receiving list of users... But how i can 
get this list just after my first client connect? 
I have service which expect some messages sends using Spread 
and several clients. Problem is that I dont want to send 
messages if server in down(or something like this:) ) thats why 
i need list of connected users.
