The latest version of TeamMentor adds the extra HSTS protection (see issue teammentor.net should use HSTS)
But what does this mean in practice?
If you look at the source code, you will see that all requests

As mentioned in the HSTS protection article, the only issue is that the first request made goes in HTTP:
