Hmm, don't know. I do know that if you have plenty of bandwidth and aren't getting a lot of uploads and/or sharing a lot of files you have a better chance of being an UP. Also if you stay connected for long periods of time it improves chances of being an UP. It can change without shutting down and reconnecting. Since I bought Pro I mostly run as a leaf. Don't know if having Pro has anything to do with it. I did read that the newer versions of LW doesn't need as many Up's to function.
