I'm having trouble, again, using the paypal portal...

...to chip in to the tip jar.

This has happened before, but sometimes I can get payments thru to DU (like my star membership), although I don't remember what that process was.

I'm trying yo use the "pay as guest" option but it just keeps circling me back around to the first page, sometimes making me jump through captcha hoops, but never actually processes the payment (that I'm aware of).

Is there any way I can just make a secure credit card payment to DU without being blocked like this?
