A moderator on Discord alerted us to a potential issue with forum registration.
We ask a number of validation questions during the registration process. It appears that these questions are perhaps not as simple as we imagined, and may present a hurdle to register for people who are not familiar with the games or who perhaps are not fluent in English, or in fact, for any of a number of reasons.
If you have registered and have a experienced issues answering the verification questions, or if you have attempted to register and failed due to the verification questions, please reach out to support@knucklecracker.com or contact me (K75) on Discord (http://discord.com/knucracker) so we can understand these issues.
And yes, this forum should also be visible to unregistered visitors. :)
