Go to http://www.rss-info.com and download RSS Editor. It’s free, and it’s pretty intuitive to use.
Alternatively, if you use a podcast production program, it may already have a built-in feed creator and editor.
You will also need to upload your podcast to a server on the internet. Again, if you use a podcasting program it will probably have a built-in FTP (file transfer protocol) facility. Otherwise you can find free ones on the web.
In order to use the FTP program, you will need to know the following:
The ftp address of your website.
The name and location of the folder into which you wish to store your
Your user name.
Caution: podcasts can take up a lot of room on your server.
