Hmmm....Well, the program for downloading a torrent is your browser
What torrent client are you using? Chances are it does have the ability to make a torrent.
There seems to be a lot of confusion around about exactly what a torrent is.... A torrent is basically a roadmap to a destination along with a description of what to find there. That's why torrent files are so small, even for a file that is gigs in size.
When you make a torrent, you are telling the torrent client to write a description of a file(which can be a program, a text file, a PDF, etc.) you have; including things like it's filename, extension, size and finally it's location in a vast decentralized network, put this short description into a file of it's own and publish the description.
If you want people to be able to find your torrent with a search engine, like Google, you will want to upload the torrent file that you made to a tracker, which is a publicly or privately accessible web server that hosts a copy of the torrent file so the servers' users can download it.
This process is quickly being replaced by the use of magnet URI's which drastically improve the life of a torrent server because evil buttheads can't shut it down for having a file that describes where to go for something you want. It would be like a cop being able to arrest you and take your property because of an entry in your datebook; "Swing by Harry's for drugs". Which could easily have meant; "Stop by Harry's Drugstore for Ventolin".
Anyway, if you want to make a torrent, open your torrent client and see if there is a "new" button in the file dropdown. If so, then you can make torrents.
When I'm done with my torrent, I will post the Magnet URI. When clicked, the forum users' torrent client (if installed) will open and download the torrent file directly from my server. Once that is done, the client will automatically begin downloading the file the torrent points to from me.
The torrent client I use is Micro-Torrent (seen as utorrent mostly because people don't know what a "micro" symbol looks like). It is small, powerful, and very kind to system resources. If I'm really getting serious about a release, I will use Azureus (NOT Vuze--it sucks) for the vast options and add-ons and what not to work with my IRC drones and RSS feeds for distribution across a wide area very quickly.
Both of these programs are freeware. Google 'em.
Oh, and I figure this goes without saying, but do everyone a favor and make sure you have something besides dial-up web service if you want to make a release. I can't count the number of scenefreaks who U/L at like 504 Bytes/sec because they are pumping 50 torrents across a 56K modem line.....
Good luck with the torrent, and PM me if you have difficulties.
