Recently I've had an increase in people asking me if they could pay for a subscription with PayPal. These requests have increased since I started the non-USA versions of the site and folks from around the world are subscribing. In some cases people don't feel comfortable entering their credit card info and in other cases their banks won't allow them to pay in USD.
So to address those concerns I've decided to start accepting PayPal for annual subscriptions. It's just annual subscriptions for now because this will be a manual process until I can get some time to fully integrate PayPal with the automated subscription handling built into the site. Instructions for paying via PayPal are on the subscriptions pricing page.
P.S. I've also started rolling out plans priced in local currencies (and currencies other than USD). Those plans will allow people to use the site's Stripe credit card form to subscribe and they'll be charged in the currency of their preference. I'll write more about those plans in the next several days.
