[Plugin: The Events Calendar] Event registration form?

Hey there Meez. At this point, the only registration component available is the Eventbrite Tickets add-on (http://tri.be/wordpress-eventbrite-tickets/). That of course would require registration be done through Eventbrite, which is possible for both paid and free events. Users can also submit events directly with Community Events (http://tri.be/wordpress-community-events/), which you might be able to use to meet these ends too.

Otherwise, though, direct event registration directly within the site doesn’t exist yet. Hope that helps and sorry I couldn’t offer up more. Let me know if you’ve got any other questions.
