Hi gang
I've tried to search for a solution to my problem but I can't find an answer. I'm sure it's probably real simple and someone out there has already used it. Here's the problem. I have an artist name of Stick McGhee or Clyde McPhatter or any of the Mc prefixes. I want to make sure the 3rd letter of the Mc name gets capitalized. How do I do it?
Thanks in advance.
Wally
