You have to re-type EACH letter in the proper UPPER or lower case as it
appears.
Some are, some aren't. I've experimented and typed them in all-caps or all-lowercase before and MOST haven't made a difference. However I don't remember with Zoto if its case-sensitive or not, and I can't test it to see because I'd have to create another account and I don't want to do that lol
