The registration instructions mention a verification e-mail, but it's been about an hour, and I haven't gotten it. I did get one thanking me for joining, but it didn't have any information on verifying. I found a link to resend the confirmation e-mail, but it said "Sorry! We're currently experiencing technical difficulties and are unable to complete the process at this time." I've seen mention of PayPal being suitable verification, so I've linked my account (which does have a card on it). Is that enough verification to start buying? Or is there something else I need to do?
