@Cara Bereck Levy, I just signed up for the new forums and was very quietly screaming in my head the entire time because I did it on my hotel's unsecured Wi-Fi.
It looks like the Unitronics website's security certificates are assigned to your Cloudflare transparent proxy rather than your unitronics.com domain. When any modern browser sees that, it warns users that your website is insecure and they should not proceed.
Fortunately (well, not really), most people won't ever see that warning, because your Google preferred search domain and DNS listing bring anyone looking for Unitronics straight to the http:// website. Even if you manually go to https://forum.unitronics.com, as soon as you click any link you're back at the insecure, http://forum.unitronics.com website.
If you sign up or sign in from a public hotspot, that means the entire exchange is sent in clear, easily sniffed/intercepted, insecure plaintext that tells anyone who might be doing evil things what your email and password are. Hopefully nobody has ever done that with a password they reuse for online banking or anything important!
Could you let your IT folks know that they may want to look at the website setup?
