From MIE Software:From the developer: ""The Summit Event Manager is easy-to-use Windows-based software that gives you all the tools necessary to organize and manage events: from small meetings to gala dinners to large international conferences--in fact, any event that brings people together. Everything is in one package. No more switching between spreadsheets, word processors, and accounting packages and retyping information.""
Note: Registration costs $1,100. There is a limit of 20 people in any event file until the software is registered.
