Our aim is to keep the database free. But over the past 2 years, monthly costs have skyrocketed. Because we had to switch from sponsored free hosting to paid (but much faster) hosting, we lost 800 euros annually. In addition, we have 3 paid plugins and the monthly costs amount to almost 100 euros. A lot of friends of the site are asking how they can contribute. That is why we have created this Paypal link. Don’t feel obliged to participate, but we will give our friends a special page, otherwise please indicate that you want to remain anonymous.
