I used my Microsoft Account (established years ago) ID /Password to sign into the link:

https://forums.flightsimulator.com/

 

And it worked. I got into my Microsoft Account.

But I did not see any reference to Microsoft Flight Sim forum.

Don't have an Xpox nor do I want one. Wouldn't another forum just be more of the same angst?

My email client (Thunderbird) didn't like the confirmation email suspecting a fraud. Holding off a little.

The mail adress is the same as the one already used by Microsoft to send the Insider Program welcome and so on. I suspect the fraud is Thunderbird instead.

Still works for me.

Pretty sure they don't want anyone to sign up yet, hence why they have hidden that link.  When sign ups are actually open it will be automatically approved via e-mail, the human verification step is only there to prevent people from getting access.
