eventbrite logoEventbrite not only sends out invitations to an event, it can be used to promote the gathering through search engines, blogs and social networks. It works especially well for events with a policy of "the more, the merrier." If the event is free, Eventbrite is free; if tickets cost money, the company keeps a small percentage of the price.
