Trouble with donating

Hello, I am a new user of the service and was quite impressed with its utility - my big regret was that it took me this long to check it out even though I had heard the name for years. Anyways, I wanted to make a small donation through the site so I dutifully entered my card details in the Stripe payment window but it states that your card is not supported. Do you support other means of payment pls, such as PayPal? I will try with a different card later as well.

Replying to myself: I guess (some credit card processors restrict certain card in certain countries) - I will try to donate using a Mastercard in a bit instead.
