There're four main user types:
User-types
----------------
Administrators - Create unlimited staff users and let them manage the platform with their own login credentials.
Contacts - Contacts are what you add from your dashboard or people who register using the registration form. Contacts user types also get a dashboard to log in on the website, submit abstracts etc. but they're not attendees and do not display in the attendee list. How to let register people as attendees? See below.
Attendees - Attendees are people who buy tickets. You can also make contacts as attendees manually by going to their profile and clicking on Make attendee button. Attendees user types are displayed in the attendee list on the website.
Reviewers - Reviewers are people who register as reviewers (to review abstracts and papers) from the website. Currently, reviewers cannot be made as attendees. In case, they're also attending the event, then they have to register as contact and then an admin can make them as attendee by going to their profiles, or, they can buy the tickets, if you have any, and become attendees.
Sub-types
---------------
Moderators - Moderators are sub-type of attendee user type. To make someone a moderator, you need to make him/her an attendee first, if he/she is not already an attendee, and then click on Make Moderator button in the profile.
Speakers - Speakers are sub-type of attendee user type. To make someone a speaker, you need to make him/her an attendee first, if he/she is not already an attendee, and then click on Make Speaker button in the profile.
