Not sure if they have been hacked but the site does not respond well to command. I had to restart my invite 3 times. Leaves a sliver of a window to add guests. I was not able remove a unintended guest and it wouldn't let me add guests. It was puzzling why when before when I used it, no problem. Next thing I know it had sent it out to all in my address book, including the person we are throwing the surprise for.
Horrible platform to send evites. What use to be easy is no longer. It was time consuming, stressful and EVITE will no longer be on my friend list.
