about uploading

what does it means - upload failed!
error:: invalid announce url! must be http://www.tribalmixes.com/announce.php
where this must be release

Well, when you create your torrent in any client, you must type the tracker url before the creation process, so it's easy, just typt http://www.tribalmixes.com/announce.php there and create your torrent, upload it here and seed

I create and uploaded my torrents correcly and they have been posted in the list of downloadable torrents but, after that, they have been deleted by the site administration because i did not "seed". What does it mean? what do i have to do to "seed" my torrents?

Jó napot:)

for others to get those mixes you need to seed torrents in your client. same as you download them from someone seeding.
