Each entity you interact with in marinemotion (stations, channels, programs, pages, users, etc.) has a friendly URL and a hashed URL. A friendly URL is easy to read and remember, but changes based on the form title. A hashed URL is less memorable, but doesn't change when the form title changes.

We can use this in various ways, but primarily your purpose for a friendly URL is to help search engines and spiders to know what it on your pages and reference them properly.
You always link to the hashed URL, and you can create a custom friendly URL in the "Path" section of the meta data column on your program editing interface.
