-## Thank you for sending in a pull request, here's some tips to get started!

 - Before starting on some new big chunk of code, it it is optional but highly recommended to open an issue first
  to say "Hey, I think this idea X should be implemented and I'm starting work on it. My general plan is Y, any feedback
  is appreciated." This will allow other devs to potentially save you time by not accidentially duplicating work etc...

 - If your PR fixes a bug, mention "fixes #bugnum" somewhere in your pull request description.
 - If your other co-developers have comments on your PR please tweak as needed.
 - Please also enable "Allow edits by maintainers".
+- Please do not submit untested code.
+- If you do not have the affected hardware to test your code changes adequately against regressions, please indicate this, so that contributors and commnunity members can help test your changes.
