If chat is added, I think we should also add an FAQ category on Fortran Discourse. Is there a way to make Discourse entries community-editable like a Wiki entry? I did not see one.
EDIT:
See What is a Wiki Post? - users - Discourse Meta
In the meantime, I added three items to the Fortran Wiki FAQ
Anyone can feel free to edit them (or add your own!).
o short-circuiting - FAQ in Fortran Wiki
o row-column array construction - FAQ in Fortran Wiki
o numbered filenames - FAQ in Fortran Wiki
