Update - Tonight there was an email that was sent out. In the upgrade process the migration changed a setting. I have corrected the issue and no more system emails will be sent out to everyone.
Update - In the update process there where several people that were registered but the settings in migrating got set to having an account but not registered. That should be corrected now.
I updated the site to help with security. So now the forums are back online. If you find any issues please let me know. Thanks
