Hi,
I tried over multiple days to register an account for the forum access, but each time the registration page would let me submit, but then return back to the same page with no errors, but some fields blanked back out.
I tried Chrome and Safari.
In the end I logged in using my Discord account as a workaround.

I had a similar issue, tried joining with Firefox and it never worked. It worked with Edge… please don’t make people use Edge 
I also had this issue, and ended up using GitHub sign in to work around it.
I am using Firefox on Linux.
Using a plugin to switch my user agent string and relevant navigator.* properties to claim that I was running Chrome on Windows did not fix this.
