More or less, you can increase the number of Ultrapeer-Connections by resetting the keep alive after you are connected to at least one ultrapeer.

You can try that if you aren't finding a specific file you were searching for. (You can even set your connections-speed to t1 or t3 and increase the number of connections to 20 or so, but DON'T DO THAT!)

You can still edit limewire.props , something everyone is forgetting .
