How do I get access to install User Gopher?

For the time-being, User Gopher is in a limited "early access" program.   Users must apply via this form and will be notified with a link to the access-limited installer link, which points to a private Add-ons Store entry. Only users whose G Suite email addresses were included in the application will have access to User Gopher during early access.

Note that we do plan to open up User Gopher to a broader beta release in early spring.
