Great! Just for anyone else…
The plugin comes with two member types – mailing list and member.
Member types are useful to segment different sections of your church community for communication – so we have Visitor, Irregular Attender, Regular Attender, Member!
To edit member types – it’s the People Tab and half way down is the section “Member Types (Click to toggle view)”
To find member_type_ids for use in shortcodes, click on the Shortcodes button at the top of the screen and they will be listed for you. One day I will get round to using member types themselves rather than their id’s!
