I think some of the previous reviewers made a mistake when they tried to compare the different services.
In general one might be right if stating that aMule is more complicated. Although I think to remember that I got an server.met file when I downloaded aMule the first time. But it doesn't matter. If someone is willing to use the app and in most cases to cross the border of what is legal, he should be willing to read a bit more about what he is doing there. And in case you are doing so, aMule is a nice product. There is still a lot to learn from its big brother eMule. But anyways the best app for this protocol. and if you are looking for some rare shit, aMule will be your friend. you will find stuff you do not find on any other network. so take your time and give it another try.
