Thanks Friction, I think I'll learn a bit more about torrents first. It's the idea of being connected to numerous, unknown computers that bothers me.
Arkbird, brilliant mate, thanks. Sadly my mobile dongle's running really slowly at the moment; I'm looking at 6-10 hours just for 3 odd gigs.
P.S. The dongle's rented from 3. Shit product, shit service!
