Well, I've been on BitComet for a few weeks now. I only download a film every other week if I want to see it and don't want to pay the ridiculous price of the cinema. That's the great part of BitComet -- it's completely free!
I totally recommend it to anyone, wether you're a computer nerd or a technophobe. It's just so easy to navigate and only takes 3-4 hours to download a film. Even my 11 year old sister uses it without any problems.
So, if you're not signed up but are considering it, then...
Consider no more!
