If you are an GEE community catalog sponsor, or someone who has submitted a dataset that has been included in the catalog you can register here to be included in the insiders program. What happens when you sign up for the Insiders program?
* You are added to a Google Group called catalog-contributors
* This will give you early access to certain datasets as they are being processed, reviewed and some unreleased yet. :)
* You will also recieve changelog and updates emails once in a while and you can post to the google group with questions, concerns and thoughts
