If so, start another thread for that. Everyone using COWOA doesn't need to be blasted with email notices about your differences of opinions.

Zen Cart should (and has always intended to) treat email addresses as case-insensitive. It is rare when it does not.
The suggestions proposed above show how to make that happen with COWOA's code as well, and I suspect the next update to COWOA will incorporate one of these approaches.
The core of Zen Cart will certainly treat emails as case-insensitive whenever guest-checkout is incorporated.
I did have a thread I started talking about whether emails should be case sensitive or case insensitive. You could have move all this extra post to it if it still existed.
