I'm getting untrusted cert warnings in Firefox. This appears to only happen on the 'events' subdomain. Normally I chalk these errors up to the insanity of configuring SSL with many web hosts and allow the exception, as IIRC Firefox is pretty stringent on cert chaining and stuff. But there is no way in hell I'm adding a trust exception for Chaos Computer Club's url.
