three simple possibilities:
1st: seed, seed seed your downloaded torrents. The more the better. When you are finished seeding: seed some more!
2nd: upload a torrent for a new video to our tracker.
3rd: Donate to our site and help us to keep this site alive on the net.
There are some other possibilities to increase your ratio, but they either depend on your user status or your seeding time.
Additional possibilities for power users: (albeit to be a power user you need a ratio above 1.05 so you will rarely need this) You can invite new users to our site. For each invited new user you'll get an upload traffic of 2 GB credited. See the topic Invitation for more details.
Seeding time: you get seed bonus points for the time your client is seeding, regardless of your upload traffic during that seeding time. The current rate is you get 0.5 points for each hour seeding. If you accumulate 100 Points or more you can exchange your bonus against upload traffic for your account (currently from 1 GB for 100 points up to 10 GB for 600 points).
