Use pingg to manage invite forwarding, and all guest list additions.

Decide how many friends each guest can bring, 1, 2, 3, unlimited or none at all. Allow names to be added to all event lists.

Allow your guests to forward invites or block with optional control settings. Either personally approve each forward request, or automatically enable them all and the names will be added to your guest list.

Set the guest limit, and add a ìcount downî on your web page. Let guests see how many more RSVPS your event will accept before it hits capacity.

Post your guest list on your event web page for all to see, keep it private or just post the ìyesî RSVPs. Enable or block comments on RSVPs.

Enable to keep guest lists hidden, and invite responses private. Only the host will see the guest list.

Add an RSS/news feed to your event web page and give guests up-to-the-minute updates on all the event details. See how RSVPd yes, who forwarded the invite and whose brining a friend.

For smaller events, set a limit on RSVPs. Post max capacity on your page, then enable a count down. RSVPs past the limit will not be honored.

Allow anyone to RSVP to your event regardless of whether they are on or off the guest list. Post your invites on Facebook, forward through friends, or print fliers with the web page URL. Anyone can RSVP to an "open event."
