The Orion's Arm Universe Project Forums

With permission from Chris Laurel, the official Celestia Web site has been transferred to http://celestiaproject.net/

The new site is being run by a Celestia enthusiast in Russia and includes a Web Forum at
http://celestiaproject.net/forum/

Many of its administrative pages were copied from the original Forum, but I declined the offer to moderate the new one, primarily for health reasons.

Excellent!
Most of the things I wanted in Celestia are available in Space Engine, also developed by a Russian; but Celestia is much easier to work with when making add-ons.

Celestia is also "lighter" -- not requiring as much out of a system. SpaceEngine is unusably slow on my computer.
