When asking for help do the following:
1) Search our Wiki to see if there's a solution to your problem - Wiki
2) If Wiki is of no help, do a forum search
. Chances are your question has already been answered.
3) If all else fails make a thread and give us as much detailed information
Help us in helping you. Do not just say "it doesn't work!". Provide details so that we don't have to guess or waste time asking. What client do you use? What's your OS? What's your network setup? What's the exact error message you get, if any? What are the torrents you are having problems with? The more details you give the easier it will be for us, and the more likely your post will get a useful reply, as opposed to a reply that just asks for more information.
