So Facebook has gone and limited the amount of invites each account can send to 100 and has also limited the TOTAL amount of invites an event can have pending to only 300! (source: insidefacebook.com/2013/04/09/facebook-puts-limits-on-event-invites/ ) This poses a big problem for big events and promoters. I happen to work for a music festival that on average has 15,000 attendees. What we are currently doing is using the events we already have and changing the names and dates of them so that people that said they were going to the last event will get a notification of the new event. Has anyone come up with a better way to do this? We're struggling and open to any suggestions. Thanks.
