This application is definitely one of the more slick ones that I have come across. The Invites application allows you to send invitations to your friends for various events. It is built on the SaKi platform and has an extremely user friendly flash based interface. After accepting an invitiation it is displayed on your profile. Ultimately this is a complete substitute for Evite except that it is on Facebook. The only feature that is missing is the ability to invite people that aren’t within Facebook. If you want a simple way to handle invites for your next event go grab the Invites application.
