I had an email yesterday from a friend/supporter who downloaded the free PDF version of KN@PPSTER's Big Freakin' Book of Stuff and wanted to pay me a little something for it (without going off to buy a different version). He didn't want to do the monthly Patreon thing or crypto-currency, he just wanted to send me a little cash.
Until then, it hadn't really occurred to me that you never see a PayPal button around here unless it's for something specific.
Duh. Fixed. PayPal is now among the sidebar "support KN@PPSTER" options.
