Sad news: Last update run was on March 30th, 2025. Some people were not nice to the waymarking.com website, and so it is no longer possible to access some of the pages without logging in. The category pages are part of these. Creating a workaround for that may take some time - even more, because I'm currently busy with other more urgent thingies. Hopefully I'll find time in May to fix that. See also the according thread in the forum.

Yours, Erik.
