We very much appreciate your wanting to be a supporter! Supporters pay for the entire site. We don't carry any annoying ads, so we don't need to scrape every bit of personal data we can about you, to sell to advertisers.
There are lots of benefits to becoming a supporter, the Upgrade page in the main menu lists them (not visible if you're already a supporter to avoid members paying twice).
You can pay by credit/debit card. Payments are dealt with via our payment processor, CCBill.
Our repeating payments come with a 100% no hassle cancellation guarantee.
