migrates to https:// only

Although has supported https:// for some time, we have allowed our users to use http:// protocols for legacy reasons. Now, our security transition has been completed: we now only support https://. 

Most users will not notice any change.

Users of http:// will need to re-login to their accounts if they were currently logged in. 

All http:// links will automatically redirect to https://, so older links will still function.

Just keep using the site as normal. If you experience any problems with the change, please report them to
