Well, there's a link to their site below. I'm not sure how much help it'll be for you, but just coming from me, I have used two BitTorrent programs, and this is the best.
Azureus
There are other BitTorrent "Clients. "
Another good one is Bit Tornado ... It's interface is relatively simple to use, but I found that it wasn't as good as Azureus at tinkering with ports, and bandwidth issues.
Then there's BitLord which is also pretty easy to use.
There are always new programs coming out that offer something better than the rest, but I stick with the more mainstream programs just because they are generally reliable.
Now Azureus does have one issue... it is Java based. This means you will have to install Java from Sun Technologies onto your computer. It's not spyware, it's not adware, its an actual program that underpins many others...
It just adds to the complexity of the program, and since you don't know that much about computers, it can be a pain if anything goes wrong.
I didn't have any problems with it, and I'm sure you won't either. But if you want true ease of use, try BitLord.
