Hi Rechenda!
I’d be happy to help with your questions.
1) Multiple attendee registration – You will need the free Events Tickets plugin in order to allow people to RSVP to the events, and Events Tickets Plus if you want to sell tickets. When RSVPing to an event, you can RSVP for multiple people at once, but it does not allow entering individual names and emails. For each person to have their own details connected to the RSVP/ticket, the form would have to be filled out and submitted multiple times.
2) Custom confirmation email – When using Events Tickets, you can customize the email subject within the admin settings. To completely customize the email content, you would need to create a custom template as is described in our Themer’s Guide, and modify a copy of the email.php file in event-tickets/src/views/tickets/.
3) Event categories – Events can have categories and tags assigned to them. With Events Calendar Pro, you can use shortcodes to add category or tag specific calendars within your site. The Tribe Filterbar will allow your visitors to sort the main calendar by these categories and tags.
Hope that helps! Please let us know if you have any other questions.
Thanks,
Sky
