In Azureus, start by clickin file from the menu bar then to new torrent (Files > New Torrent) or you can just click on the 5th icon right below the menu bar, the one looks like a white sheet of paper with a fold in the corner (create new torrent). After you click on "create a torrent" a window will pop-up, there make sure you have the radio selected for "use an external tracker". Right below in announce URL put this
http://tracker.banglatorrents.com:2710/announce Leave everything as it is and only thing you need to check is wheather it is just a file you are uploading or a directory (meaning a folder), then click next.
Next window ask you to locate the file or directory, click on browse and then locate the file/directory, the address of your file (ie. c:\download\natok.avi and for folder c:\download\thismp3folder ). The click next.
In this window, leave everything as it is. Piece size = Auto and make sure everything below it is UNCHECKED. And now you are done, hit finish. After it finishes, hit close. A new file with the same name as the directory or the file (ie. natok.avi, but actually a torrent file) will be created, icon of that new file will be the azerus (blue frog) icon. That is the torrent file that you would need to post in your thread as attachment. After you have successfully attach the torrent file, immidiately go back and delete the torrent file from you harddrive (delete it from you computer after you attach it in the thread).
Now the easy part! come back to your thread, where you have attached the torrent file and click on it to download the file (yes, just like you would do if someone else have released it). The only difference is this time you will tell Azureus to save the file in the same place as it already exist in your harddrive (kinda like overwritting the existing file). Don't worry it will not start to download the whole file, instead Azureus will recognize that they are the same file and create a new torrent file (you dont need to worry about after you click save) and start to seed after the checking is complete as explained in the last picture below. And that's it, leave your Azureus open and people will download from you in no time. However, you must have your firewalls setup for Azureus to function properly if you have tight security settings.
