How does the Community feature work?
 

It doesn't seem to have any effect for me. What can I expect from this feature? Does it only work if the other Gnutella clients are LimeWire too?

This is how I do it

Select the group you want
Then click the logon button
Wait for the connections to rise
Sometimes lucky, sometimes not!

I had great success in Australia when I couldn't get "Fragma" from anywhere else.
