I2P seeding must use the Postman tracker, as this tracker is the only source of information for I2P Bittorrent users. DHT and open trackers do not get information about new torrents across.

Full fledged I2P Bittorrent SW intended for seeding must do the following:
- include a Postmann announce URL in the torrent file by default (like "http://tracker2.postman.i2p/announce.php"). Otherwise the torrent cannot be uploaded to Postman and nobody will know about it. Currently the Postman tracker URL must be inserted manually in Tixati.
- announce the torrent frequently to this tracker URL. Otherwise Postman will not show the torrent on his website. As far as I can see, Tixati is currently unable to announce to the tracker at all.

Be sure to upload a fresh Tixati torrent to Postman and start seeding. When Postman shows a green light for your torrent, you are done.

apart from dg2 no publicly available I2P opentracker is working in Tixati 3.35
