I like how easy it was for me as an organizer of my own event/workshop, or even just meeting with other people who are organizing their meetings (or workshops).
It's super simple! The only thing you can't do in this program if your not using Google Calendar - but there should be some way around having all those different calendars open at once while working within one platform? So far we've been able use our google calendar easily from here too which has helped us keep track easier than before when doing things outside through emailing files back-and forth between 2 parties etc..
