Sharing new data with other geoTorrent.org users is easy.

It is a simple 3 step process:

1. Create the .torrent file
2. Upload the .torrent file to the geoTorrent.org server
3. Begin seeding your new torrent.

Create a torrent file

1. Decide what you want to share. A torrent can contain either a single file, or a directory of many files. This is often quite convenient, since it avoids the step of creating an archive (.zip, .rar, etc.) if you need to store multiple files.
2. Run your torrent creation program. Azureus and bitlord (two bittorrent clients) have inbuilt torrent creation utilities. They are located under the "file menu". Alternatively, you can download a specific creation utility "makeTorrent" (http://krypt.dyndns.org:81/torrent/maketorrent/)
3. Enter the tracker's announce url in the space provided. The announce URL for geoTorrent is http://www.geotorrent.org/announce.php
4. Follow your torrent creation utilities interface through to completion. Apart from the settings mentioned here, you will can just follow the default settings in the torrent creation client.

Upload the .torrent file to the geoTorrent.org server

1. Ensure that you have "uploader" privelidges to geoTorrent.org. You can get these by contacting info@geoTorrent.org
2. Visit http://www.geotorrent.org/upload.php to upload the .torrent file to the geoTorrent.org server.
3. Fill out the form with the necessary values and click submit. The more information you can provide the easier it is for people to decide if the data you are sharing will be useful to them.

Begin seeding your new torrent.

Until this step, nothing but metadata has been transferred. Seeding is necessary to actually transmit your file to others. There are several ways to do this, but the simplest is to use your ordinary BitTorrent client just as you would with any other file. Navigate to the page on the web server where your .torrent is posted, click the link, and when the BitTorrent client starts be sure to select the same file/ directory that you used in maketorrent in step 2 above. The client should check the files and verify that they are complete, and then connect to the tracker and begin seeding.
