The Paypal contribution link for this site is in German and the number has a comma. I’m not quite sure what I’m donating. Is there a US version with dollars?
The comma in German is the same as the decimal point in English:
I see there’s an English language drop down option on the Paypal page but it doesn’t change the currency format.
As Proleric says, the comma is a decimal separator in German (and many other international numbering systems), and the period/dot is a thousands separator. So just flip the roles of those two symbols from the US version.
There’s also a Patreon available in USD: https://www.patreon.com/nwn/
Yes, I opted for Patreon. It expects a monthly payment, but if like me you prefer to make an annual donation, you can pay it all in one month, then cancel.
