The contributing page on the website reads:
Before creating your pull request, it’s usually worth asking other contributors if the code you’re planning on writing will be considered for merging.
The contributing.md guidelines in the repos usefully add:
“You can do this by opening an issue and asking.”
It would help to know to open an issue as the way to ask. Can we add this to the contributing page on the website? We don’t need to link to a particular repo’s issues page. If we also want to direct folks to the forum, it might read: “… an issue in the appropriate repo or posting on the community forum.”
