Yeah Torrenting is as easy as opening a file in a program, I know I tried to 'explain' it all in another thread but that was all background fluff that you don't really need to know.
Azerus is by far the best client out there, but you pay for it with it's memory munching tendancy and you need Java installed on your machine to use it.
If you are looking for a quick and easy sure fire method of getting them download Bit Tornado, install it, then click on the torrent from the page above and it should pop up a "open with or save" dialog box, just select open with then select Bit Tornado and then it'll load up Bit Tornado and ask you where to save it. Then jsut wait for it to be done.
