If you contribute in some way to GNOME, are you already a GNOME Foundation member? If not, you should apply ASAP: https://foundation.gnome.org/membership/
Once you do (or if you’re already a member), don’t forget to VOTE in the upcoming Foundation elections!
The GNOME Foundation Board of Directors is elected by Foundation members. If you want to influence how the Foundation is run, one of the most effective things you can do is to become a member and vote.
