Hello Kvetch!
I am afraid that 4D is definitely dead, even though it's not officially buried yet.
I pop in myself, about once a year, and there is never anyone on line. So starting to build here, would be an enormous waste of your time.
Too bad, since it was a wonderful Mud, but I don't see any chance of reviving it at this time, when Text Muds mostly seem to be a matter of the past.
But lovely to see an old player log on anyhow!
love, Molly
