I have now written over a dozen PLATO terminals for IRATA.ONLINE, and have been ceaselessly promoting them for months...but have received almost no testing feedback, save for the Atari 8-bit version... if this were a capitalist enterprise, I would cut my losses and pull the plug on the whole thing.
Yes I would probably do something similar if I had the interest. Generally I know the feeling from when people are asking of something, you make it work and publish it, and then crickets regarding feedback. Usually I find use of my own work at least.
