Any way to customize standard OWC meeting invitation emails
You can certainly add a custom feild as an Account admin, but you can just use that to define sort order in the attendee pod. You cant hide a name from attendee pod, but yes as a host you can edit users info and change their names. OR, if you dont want others to see the attendee pod, you can move the attendee pod to Presenter only Area (POA).
Hope that helps!
