We are hosting a halloween party.
<p>We have members in our shared site and we just announce that we are having an halloween party for our members.</p>
<p>We would like for them to RSVP to us is there such a thing in the shared site where members can rsvp and tell us how many are coming from that family so we can keep track of how many are coming?</p>
<p>I thought I saw it somewhere and now I can't find it.</p>
<p>HELP! RSVP is October 19th.</p>
