If you have a web page up for it, please let me know and I'll be happy to add it to my list.
Actually, the vast majority of the VTs listed are dead or abandoned projects. And about half of the remaining ones are still in development. I should probably revise my list soon to indicate this.
Thanks for the heads-up about the WebRPG link being dead. That must be a pretty recent development, because it was working less than a month ago.
