Hi, Mo - the Introduction is the introduction to the FAQ. The Wikipedia article is a pretty good description.

Here's the very first thread from Mudcat (don't ask why it's thread #4):

https://mudcat.org/thread.cfm?threadid=004

As you can see, it has no set purpose and no set rules, just a discussion forum built around a folk song database. There are those who specify what mudcat is and what it isn't, but I think most of us appreciate its lack of structure and purpose. It has been growing organically for 27-1/2 years.
