Yup. We got hacked. The whole site all around. They even changed the Uniform Server download link on the main site to a fake download & application, deleted the Forum and content and messed with the main site and come cpanel configurations.
Don't know how this happened, but we are so sorry.
Unfortunately all forum attachments are gone, so are avatars and profile pictures unless you are using your gravatar account, so please be sure to set those back.
We have restored, everything with fresh versions since no backups were kept so bear with us as we get things back up and running.
