If you want event management with event discovery, eventbrite is the way to go.
I love Eventbrite.. It is so easy to use and has direct integration with Google Calendar... Nice!
It has all the features I need for mutli-participant workshops. It integrates well with calendars on the attendee side and various CRMs and other apps (via Zapier) on the event manager side. Completely mobile-friendly, yes! (I tried Eventable but not quite as feature rich and iOS / Safari friendly as needed with date-pickers.)
