Organic groups RSVP is an RSVP extension for the Event module specifically tailored for inviting Organic groups. OG RSVP implements an easy-to-use interface for invitations and RSVPs by using Organic groups Audience form and displaying the RSVP status form directly on the node respectively.

Member RSVP status can be displayed on group content directly or in any number of views a site administrator can think of such as "My Pending Events".
