Transmission

Sorry, this is not really related to Transmission itself, but today I created a torrent file (including a punch of trackers) and made an entry at kat.ph.

I even deleted my own torrent file after creating the entry on kat.ph and downloaded it from there again. Transmission instantly recognized my file, validated it and displays me as a seeder, but no tracker can find me as a seeder. My file is just not recognized as a source.

What did I miss? What do I need to do in order to become a seeder of my own creation?

I moved the file and re-validated the local data. No change. But Transmission itself didn't have any problems with my file anyway. It's only the trackers not seeing my computer as a source for this particular file...

kat.ph now sees me as seeder if I login at my account and browse to the file. If I search the normal way for the file (without using my account) it doesn't find a trace of it.

Is there any definition I could have messed up when I was generating the torrent file?
