It would be helpful if there was a way the participant list could be available "offline" for checking in at events.  We recently had an event and used the Event App.  It worked great up until the point that we lost internet connectivity.  At that point, we had to scramble to log a note of those coming in while we waited for the internet service to be available again.  Sometimes, we host events in buildings that don't have good cell reception and it would really help if we could have some way to do this and then have it sync back to the online database to update the information with those who attended.  I'm not sure how easy it would be to do something like this, but thought I'd put it out there.
