Grenadine

Grenadine Event Planning Software is a web based convention programme planning tool developed by Henry Balen from 2010 for Renovation and now sold commercially, with reduced rates for fans. Its been used for all but one Worldcon since 2011, and some 50 other cons round the world.

It produces confirmation letters, programme grids and listings and can be accessed through websites or a mobile phone app, another example of technology leading to the decline of the traditional paper ReadMes at conventions.
