Click on the banner with the bandsaw above, then change the number to 20. Click Save. You will get another screen to fill in your credit card info. We do not have a direct way for PayPal at the moment.
If anyone prefers to make a direct donation, there is a Donate/Pay button on the Menu bar where you see Forums/What's New/Media/Resources/etc. You may have to use the arrow to scroll over to see the Donate menu.
This still uses credit card processing, not PayPal, Venmo, or Zelle.
