I did, and it seemed relevant, but I didn't understand it. The page says "If passed in, the 2nd argument should be a module or package to be used instead of twisted.plugins as the plugin meta-package." I had no idea what such a module or package should do! Reading the section above seemed to make it clear that I could mkdir -p twisted/plugins and drop my code in there.

And thanks for this too. I'm very new to python, and I had no idea. The code is now working. Terry
