I did for one. The paypal link was a bit confusing in that the link did not recognize my account (I checked the "I have an account" and could not log in). Once I marked the "I don't have an account" link, I was directed to paypal's site where I could log into my account and make a donation. The donations are in British pound domination; however paypal does the conversion to USD.
Quite a few have donated which I was happy to see.
