How Can I share files that I downloades?

I have download some files, but these files arenīt shared. I mean that the upload is always in 0 kb/s
I donīt know the reason...
Any idea?

only dld the files that has more leechers

All you have to do is make sure the torrent file is open in the same are that your downloading it in your Client. So dont push the finished button or anything make sure you leave it there after it has downloaded and seed it until you get results. You should have a upload and download rate at the bottum of the progression bar if you have left it alone.

if u leave ur file open with ur program and the upload speed is always at 0 it means nobody is downloading it or that u r not connectable, check faq and rules
