For example, this link tells you roughly what is actually available on alt.binaries.starwars and this link shows what is available if the words "star wars" are typed into the search field.
I also have another tip for those UK based ntl customers that I know come here.
The ntl servers have been rubbish lately and have come back to form in the last day or two but thier retension at the moment is lousy.
For some reason, if you use news.virgin.net instead of the usual ntl server, it works, its free and the retension is far better.
This may have been a stop-gap arrangement during the ntl server problems so it may not last.........
