[Spread-users] Getting started with spread

[Jonathan Stanton]

If you want to receive the messages you send, you will need a program (maybe the same one) 
that joins the group and then receives messages sent to it using either the 'receive' 
method or by creating a listener thread. 

The best example would be to look at the User.java sample program in the Spread source 
distribution. It can send messages to groups and will receive and print with formatting 
both data and membership messages that are received. 

Cheers,

Jonathan
