Thanks to Dano I've been able to compile into one global Action all the tag edits that I want and/or need.
Fearful that if for any reason I should have to re-install MP3TAG, I would like to be able to have a "backup" somewhere where it could be reinstated into the "new" MP3TAG should the need arise. Can someone please tell me where the Actions are stored?
Dano, thanks once again for your help, patience and tolerance!
