Hi Bill,
Are you posting the "payments received" status for each order / user somewhere? If not, doing so might be helpful.
While I
think I paid, perhaps you overlooked it (or maybe Paypal whacked out on the payment or something). If I knew you hadn't received my payment (though I made it), I could chase it down & make sure you got it quickly...
Also, "friends" might help others get their payments in (if you know what I mean
).
