@projectmesa/maintainers kind reminder to check your name/orcid/affiliation and hit the checkbox. If you are in doubt on something, need a little bit of time, don’t agree with something or don’t want to be on the paper that’s fine, but please just communicate something. Feels like talking to a wall sometimes.
