in reality it is two things
1. the current generation of internet browsers are building in more and more security, and that leads to point 2
2. there are digital "certificates" that proclaim that the ownership of the site has taken steps to secure the site in regards to personal information.
We are aware that we need such a certificate and it then just needs to be added to the site.
But with everything that has been going on in our lives, Jason and mine, we haven't gotten around to applying for, paying, and ultimately adding it to the forum.
A simple fix to not see that warning, just stay logged in all the time(most of us do so anyway)
