Registrations for the old Warrior’s Wish forum have been disabled (temporarily?) due to it being mostly dead. You’re more than welcome to sign up on the main site, but you will not be allowed to register for the old forum anymore. That being said, if you already have an account, you can certainly still sign in. This is mostly just to prevent the influx of spam bots that tend to come around when forums die, but if there is newly generated interest in the old forum, registration may be reopened.
