I would recommend adding an SSL certificate for the forum.dronedeploy.com forum.
Not only would it increase your ranking in Google search results (since they favor SSL encrypted sites) but also because currently the account creation and login forms are completely unencrypted. For many web browsers, they now display warning upon logging in that the form is not encrypted and should not be trusted.
I know, it’s a forum, not a bank, but security is important everywhere
