The MindBody integration will also allow you to add btwb accounts to a Whitelist or a Blacklist.
btwb accounts that are allowed in your gym regardless of MindBody subscription status. An example of someone you might add to your whitelist is an ex-gym member that no longer has a MindBody subscription with you, but who still wants to follow your gym programming.
btwb accounts that are not allowed in your gym regardless of MindBody subscription status. A blacklisted member is immediately removed from a btwb gym and will not be able to regain entry.
You can add members to either list from the "Synced Members" sub-menu page from the MINDBODY menu item.
