If it's a code change please check the boxes which are applicable

• For the main program: My edits contain no tabs and the indentation is five spaces
• I've read CONTRIBUTING.md and Coding_Convention.md
• I have tested this fix against >=2 hosts and I couldn't spot a problem
• I have tested this new feature against >=2 hosts which show this feature and >=2 host which does not (in order to avoid side effects) . I couldn't spot a problem

Hi @corydalis10 ,
Thanks. I appreciate any corrections.

However there are a few points:

• Pull Request: Why uppercase?
• participation: I´d rather leave this.

While we are at it:

• Travis is not anymore in use. We use GIthub actions
• contributions via email never happened, so that we can remove
• Headline can be a verb as the file name "Contributing / participating"

Then: I am not a native speaker and the rules for English commas are sometimes not obvious to me. But why do you put a comma after the "for ," pull requested sounds not good, though google means it exists

I've made all the changes you requested! Please review again.

This feels weird to me. But I'll leave it because it makes sense with or without the comma.
