Can someone point me to where in the UCCC there might be some information about skip payment programs?

I assume you mean in regard to charging a fee for permitting a borrower to skip a payment? Look at 5-2-202 Additional Charges - if the charge is permissible it's listed here. Also, check out 5-2-204 - Deferral Charges. This second cite would permit you to charge a payment skip fee if you're doing pre-computed loans (the face amount of the loan is the total of principal and interest to be paid).
Otherwise, I think you're out of luck. (Unless you're a national bank that is!)
