When I try to login using the Login/Password are on the left side I get an error message "Your registration process is not yet complete! Check your email for further instructions." I don't get an email. When I use the area on the top right I am brought to the old site, when I hit the browser back button I get the new site and when I hit the new site home button I am logged in.
This is strange and I wonder if might be my browser (Firefox) or if it is indeed the new forum.
Just my observations.
