Something is screwy with the passwords. From what I can tell, PayPal changed them all without warning. I have no idea what's going on.
The password you've been using is still the one my site recognizes, so long-term readers should have no problem. There are new subscribers who may not have memorized their passwords yet, and who may check PayPal and try to use the new one and get locked out.
I'm going to ask PayPal what they're up to, and decide how to proceed from there.
Thank you to everyone who's been enjoying the print version of Volume 2! I really appreciate your support! Yes, an e-version will be available soon.
