The forum's HTTPS security certificate expired expired this morning.

It was supposed to renew automatically but it didn't happen due to server issues at the certificate supplier.
Most browsers will complain that it's dangerous/insecure etc etc but it's fine, all it lacks is a digital certificate, so feel free to add am exception to override the nag from your browser.
Hopefully the certificate will automatically get installed at some point today (Sat).
Cheers
