"Lying in a featherbed will bring you no fame, nor staying beneath the quilt, and he who uses up his life without achieving fame leaves no more vestige of himself on Earth than smoke in the air or foam upon the water." -Dante Alighieri
We've done the best we can to ensure nothing will cause a half-secure connection (some non-SSL items loading), but some things still might. If you encounter any half-secure connections (excluding embedded images in forums posts), please be sure to submit a bug report.
Update: We've now employed a Wildcard Sub-Domain certificate across our SSL-enabled services (web, IRC, soon to be many more) that is Comodo-signed. This will enable us to provide trusted SSL communication encryption on many, if not all, of our services.
