// 08-07-02 preachers loaded
// 28-07-02 Version 1.1a now has landed. hides today if after 13:00. version 1.0 now archived @ /scripts/1.0/preacher.js
// 28-07-02 new format for id. date-DD-MM-YYYY . Old method still works, but this is tidier

// 03-01-03 Work on 1.1.1 to work with new markup scheme.
// Rational for hiding content from new brwosers is that it looks tidier to have only the next two month's services visible, and adding them with javascript and the dom would be an accessibility problem. || 25/07/02
