// eMail Obfuscator Script 2.1 by Tim Williams - freeware
// Modified by Steve Hunt

// The coded email address is passed to this function as a parameter.
// Each character of the encyphered address is replaced by another
// character, offset from it in the cipher string.
// The offset for the first character is determined by the length of
// the address; the offset is incremented by 1 for each successive
// character.
// Characters which do not appear in the cipher string remain unsubstituted.
// Finally the HTML anchor mark-up is output using "document.write"
