Email member and have them create (or change) the A record for the domain they want to use to point to 50.116.39.12

Then, in the WP Engine dashboard:

- click on the property name and then "domains"
- click on "add new domain" and enter the domain you want to add, at this stage you can also redirect other domains to the domain you're adding (e.g. citylimits.largoproject.org or www.citylimits.org) and it will pass these through to the primary domain you've added

In the WP Admin:

- from My Sites > Network Admin > Settings > Domains under "new domain" add the site ID and the domain you want to map to that site ID ("primary" should not be checked)

[prefix] is needed to push the new users/usermeta values outside of the range already populated in the database, usually for a site with an ID of 40 using 40,000 will work pretty well (unless some of your sites have a lot of users).

UPDATE wp_users
SET ID = ID + [prefix]

// Add two columns to the end of the wp_users table, spam and deleted. Both are TINYINT(2).
 
UPDATE wp_usermeta
SET user_id = user_id + [prefix]
