We're getting word that people are having trouble logging into the Wargamer to leave comments and participate in the forums. Turns out that it's our fault. Over the weekend we enabled cookies to allow logins from different domains and it messed up the login for people who have existing cookies with the site.
To fix the problem, simply delete your cookies from the Wargamer and try to log in again. This should enable you to login as if nothing happened.
Sorry for the inconvenience!
