How do I know someone got my chat message?

Just type the @ symbol to Mention anyone in a chat or @Everyone to notify all members in a group chat. In an event chat, the host and co-host can message @Everyone or by RSVP just type @Attending @Undecided and @Declined. If guests don’t have the app they will be notified via text message or email, if they do they will get a push notification.

How did we do?
