1. Activate the Connections screen by opening the View pull-down menu, then re-enabling Connections.

2. In the Connections screen you will see your Gnutella "role" listed in the lower left corner; this normally says [Leaf]. Do not confuse this with the connection-type listed for the external hosts you're communicating with. Normally, you'll only see one connection listed and it'll be labeled Ultrapeer.

If you have a faster-than-modem connection and you stay on-line for more than a day or two, you'll switch from Leaf-mode to Ultrapeer-mode and your Connections screen will fill-up with other Ultrapeers and 0.4-type hosts plus up to 50 Leafs (who are subordinate to you).

FYI - I think there's a bug that prevents you from properly disabling Leaf/Ultrapeer mode.
