Starting from your dashboard, you can simply click BPM and then "Add Invite" to add an invite to an upcoming BPM.
Simply select the BPM date for your upcoming BPM and then select which BPM you are inviting the guest to. If there is no BPM for that day, you may need to ask your SMD if they have setup their bpm schedule yet. This must be done before you can start adding names. If you are an SMD, you can setup your BPM schedule first.
On the mobile app, it is just as easy. Simply go to the navigation menu and click "Add Guest" and fill out the form the same way.
After adding your invites, you can click on BPM > Captain's List to see the names you have added.
