U3DA's history is TrueSpace so most of its content is too. TS is gone. There will be few new users. Old TS'ers have and will fade away from TS. That's why there is no one here. The web friends Steinie calls the "dirty dozen" still drop in but my hope that U3DA would continue with those who find it a friendlier place for CG regardless of software isn't happening.
To all the CG artists who moved to other software and other forums or websites: You are welcome here too.
