I would like to be able to access billing information. I don't like living in the dark with regard to such issues. I don't remember when exactly I paid last time. I know you guys are supposed to remind me , but e-mails get lost, or deleted by anti-spam software etc. I don't want to wake up one day and see my account canceled.
Also, more payment options. I might go to Russia in a few months which means I'll most probably have to cancel my account here, which I'd hate to do. But PayPal doesn't accept credit cards from many Eastern European countries for some weird reasons, and if you use the "Verified by Visa" thingie I won't be able to pay directly either (I'm not sure about MasterCard though, this may still be an option, but the problem is that you never know such things until you try to make a payment. )
