I think that list is tied to the Uplink PC... there hasn't been an uplink report here posted since June 21, so I would think that is all tied to the same system. In another thread, Scott said he tried contacting the person who runs it and says he has been unable to get a hold of him for over a year.
In reality then it really does not matter how up to date the list is, he can only get what he gets on those satellites. It could be a help I suppose if he thinks he should be getting a channel and check to see using the list. I think we all do wish there was a way to get up to date uplink changes and then that would result in a totally up to date list however.
