From a project team member:

"The site is not back (yet?). The domain is currently being used for the development of UNIT3D's Tracker Software focused on Music - as opposed to Movies and TV. You will see it is called UNIT3D-HiFi

Glad to see there is still love for Redtopia. It may return one day, but today is not that day. We are only about a week and a half into development of the Music tracker software and there is a lot more work to be done. As well, even with the software completed, Redtopia will need other things such as a Server, Moderators, Admins, and Finances in order to be relaunched."
