Greetings.
Emergency maintenance has taken place to update the forum software to close massive vulnerabilities that were threatening account security, as well as to make the site safe to use in modern web browsers. As you can see, this has caused a number of things to revert to default settings, including the forums theme. This was an unexpected issue, and we will be working on restoring or correcting settings, but it will take time and I do not feel that it is necessary to keep the site offline during this process.
All user logins should be the same and all accounts should have the same permissions. No threads were lost during the upgrade process. If you notice anything missing, please contact staff.
I apologize for the inconvenience. We will be working to restore the boards to working order as quickly as possible.
