2 things I can think of that you are doing wrong, not searching for related topics before starting a new one, and when I look at your tracker profile, it says you arent seeding anything right now, but that doesnt really mean you havent tried.
The first thing I will say is this; just becuz you want to seed a file doesnt mean you will have leachers who want to receive data from you.
I can DL a file from BBT at max speed, but I might have to keep that same file seeding for a few days before even one person wants data from me.
with out leachers, you cant seed is the moral of the story.
otherwise, check your torrent program preferences and make sure you dont have a cap on your upload limit.\
after taking a glance at the files in your trackers leached section, it seems like you have some files that would likely get you a reasonable number of leachers. Make sure your upload limit isnt capped, and then just seed away. but as I said before, dont just assume you will be uploading data simply becuz you are seeding.
