Thank you 'mom.
I followed the links and it all (well, most) seems to make sense. I have a couple of areas of confusion:
Area 1
Indexing. You said " I don't believe that the admin indexes originals, so your songs will not likely make it to the public Chordie search making it easy for all the people of the world to search them on Chordie (but they will be able to see, play and enjoy them if you find another way to use the links)."
That seems strange as Chordie is full of warnings about copyrighted material.
Area 2
Indexing. In the ukes4fun Part 2 link it says "This does NOT mean that your song has been indexed by Chordie, ie. if you use the Chordie Search function you will not immediately find your song in the Chordie database. Eventually, Chordie will find your song and it will be indexed."
So does that mean Chordie will eventually index original songs if I put them in my songbook and make them public?
I guess I will need the {st:xxxx} directive in my files to give an artist name.
