I'm trying to use Transmission 1.54 on Mac (Tiger) to create a torrent file to send to a friend so they can download a chunk of files from me... I'm using OpenBitTorrent as a tracker and it created it fine, checked the file and started seeding. I sent the torrent file to my friend, and it opens in Transmission at his end okay but he can't find me as a peer to download from. I've tried ticking the "Private torrent" box, and having it public, but it doesn't seem to make a difference (I don't understand what it does anyway?!)...
Is it more complicated than this? Or is there a cure?
Thanks for your help!
