We are switching our payment handler from Google Wallet to Stripe, due to the planned retirement of the Google Wallet for Digital Goods service (which we currently use). As such, we have temporarily disabled the supporter center. We should have it back up and running in the next week or so, and you can make your contributions then. 🙂
We apologize for the inconvenience, and thank you for your patience while we test the Stripe integration.
By the way, thank you for offsetting almost $1,000 of our operating costs! You can check out the spreadsheet here, if you’re interested.
