[Spread-users] Identifying the sender

[Gustavo Castro]

Hello, i´m a newbie with the spread, so this question should be easy. I have 
a spread group, let´s call it "Test" with 5 members, name A, B, C, D and E. 
If one of the members send a message, how can i know who is the sender? I 
mean, if A sends a message and E receives it, how can E possibly know that A 
was the sender? And if it was a multicast?
Thanks in advance!
