function mangle() {
	if (!document.getElementsByTagName && !document.createElement &&
		!document.createTextNode) return;
	var nodes = document.getElementsByTagName("span");
	for(var i=nodes.length-1;i>=0;i--) {
		if (nodes[i].className=="change") {
			var at = / at /;
			var dot = / dot /g;
			var node = document.createElement("a");
			var address = nodes[i].firstChild.nodeValue;

			address = address.replace(at, "@");
			address = address.replace(dot, ".");

			address = address.replace(at, "@");
			address = address.replace(dot, ".");

You can use this script, if you'd like to post your email address to your homepage, but don't want to see it picked up by spammers.

Just run it in your onload event handler and mark emails in your HTML as:

      markos at gaivo dot net

This way they are still recognizable by those who don't use javascript.
