Previously, data.world used the words people, contributors, invite, share, and a few other names in various places in the application, which caused confusion.
We now use Members to show the users that are part of an organization, Access as the tab where you can manage access at a more granular level on datasets or other resource pages, and Grant access as a consistent call to action to add additional members.
Also, the Member organization role has been updated to be Basic member to be clear and unique from members more generally.
