Iām not the biggest fan of the idea of passing authentication cookies around in the clear after we authenticated over at Sense, then are handed back to http:// for the forum.
The certificate in use at https://home.sense.com is a wildcard cert with the *.sense.com subject name so you even have a cert you could consider using.
The folks over at community.rachio.com use the same forum software and recently enabled HTTPS.
Thank you!
