There’s now a donation page up — http://writeups.org/donate.php .
As noted on this page the costs of running the site are becoming a problem, especially since we never took donations during the previous 12-15 years. These things tend to build up.
More details on the donations page. A “donate” button will be added to the site when the webmaster is done preparing a huge pile of illustrations for new and revised entries.
Please help us keep the site running ! Thank you.
