Er, theres a way to do it without verifying your bank, but you do need to make a Paypal account.
On the main website, click on the left hand side menu "How to Donate"; then enter in the space provided how much you wish to donate.
Then after pressing Add Credit, you should be taken to a website showing this:
If you do not see that, but rather a few stuff on the left and then on the right hand side a log-in window, then look on the left for a link that says "Continue Checkout.
It should say something like:
Why use PayPal?
- Use your credit card online without exposing your card number to merchants.
- Speed through checkout. No need to enter your card number or address.
Sign up for a PayPal account and continue checkout.
Continue checkout should be in blue as it is a link, and that will send you to the picture menu that I screenied, and then there you can just proceed to fill out the information without having to make an account.
Doing so will not require you to have your bank account Verified, but you will make an account in doing so. (It doesn't do you any harm to make one)
