EventOrb is an event marketing portal that provides the necessary tools to event promoters to help them publish, manage and market their events worldwide. EventOrb treats everyone that signs up on the site as an event promoter, whether they are an individual or a professional organization promoting an event. It also allows users to grade events using a trademarked weighted average called the Event GPA. Each promoter has a Cumulative Event GPA that advertisers can then in turn use to select which promoters they want to advertise with.
