// The Editforms extension is developed to enable 
// different types of input for a Wiki. In this way
// a Wiki could be build up much faster, but also 
// with more quality and clearer structure.
//
// See http://www.leerwiki.nl for either updates
// or other extensions such as the Ajax Rating Script-,
// Image shadow- or EditpageMultipleInputboxes extension. 
// good luck with your Wiki!
