Hello, first I’ll say I love what you guys are doing with Mycroft!
When I first tried to visit, i typed community.mycroft.ai into my address, naturally it defaults to http instead of https. I would recommend telling your Ubuntu Apache server install to redirect http to https. The site does not display properly under http. http://stackoverflow.com/questions/16200501/http-to-https-apache-redirection
I ran into the same issue with the activation email link.
