Greetings,
I noticed that the only option for payment for donations is by creditcard.
That is very American, but in the EU, a creditcard is a card which you pay 20-30 euros per year for, but don’t need for anything at all and registers this as a debt (at least in my country), which is unwanted unless you need debt or travel outside of Europe.
For EU costumers, a different option for payment could be used. Paypal charges a fee, so it is probably not the preferred option, but at least we people without a CC could donate. Direct bank transfer is also an option.
Just a thought.
