The site's down, but our old parent site's been that way for nearly a year.
We're working on three projects simultaneously right now, and while it's not the most important one to us right now, we're still working on G.S.T. Many G.S.T. 2.0 features are nearing completion.
Keep your eyes out for the site over the next few weeks as we try to track down some new hosting ready for the next release.
Remember that the mod is still downloadable from fileplanet.
