Not only is the option to "Sign Out" hidden under a completely unintelligible symbol to the left of one's avatar (instead of being under the avatar itself, as in most other fora), the various "Sign in" buttons don't work at all in my installation of Firefox 70 running under Windows 8.1. Clicking on them just refreshes the current page, but doesn't change anything. The only way I managed to log in to post this message was by digging up the URL "https://www.tomtom.com/uam/UI/Login
" from my browser's history.
P.S. The link at the end of the post "Welcome - please read first!
" appears to be broken.
