// Something to dynamically generate mailto:links, which should prevent spam harvesters getting at the links.
// Pass it as many arguments as you like.  The LAST argument should contain the user, and the first argument contains
// the string you wish to appear between the <a>...</a> tags (pass an empty string if you want to show the email address).
// eg write_maddr('', 'bl', 'emoon.', 'ne', 't.nz', 'dmann');
// will generate: <a href="mailto:dmann&#064;bluemoon.net.nz">dmann&#064;bluemoon.net.nz</a>
// or write_maddr('email me', 'bl', 'emoon.', 'ne', 't.nz', 'dmann');
// will generate: <a href="mailto:dmann&#064;bluemoon.net.nz">email me</a>
// (note &#064; = '@').  I avoid specifying the '@' anywhere in the HTML or javascript as it's a big red flag for harvesters.
// There must be at least 3 arguments or the function will do nothing.
// It is advisable to use a noscript tag for non javascript browsers.
