So apparently the module site https://www.exotica.org.uk (https://www.exotica.org.uk) is down, and has been down since December 1. Does anybody know about this?
Technically it's not down, it's just their SSL certificate that has expired (you can add an exception in your browser to temporarily allow the expired certificate). I'll notify the site owner about this.
All right, the site's available again.
