Here's a quick script that should do the job:

code:

---

var PSM = "Alexa Rank: %alexa%";
var URL = "www.google.com";

function OnEvent_Initialize(MessengerStart) {
    if (Messenger.MyStatus > 0) {
        MsgPlus.AddTimer("UpdateTimer", 1800000);
        UpdateAlexaRankPSM();
    }
}

function OnEvent_Timer(TimerId) {
    MsgPlus.AddTimer("UpdateTimer", 1800000);
    UpdateAlexaRankPSM();
}

function UpdateAlexaRankPSM() {
    var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.open("GET", "http://xml.alexa.com/data?cli=9&dat=nsa&url=" + encodeURI(URL), true);
    xmlhttp.send();
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            Messenger.MyPersonalMessage = PSM.replace(/%alexa%/g, xmlhttp.responseText.match(/^145 (\d+)$/m)[1]);
        }
    }
}

This will update your PSM with your site's Alexa Rank every 30 minutes. Just change the highlighted red text to your own custom PSM (where "%alexa%" will display your site's ranking) and your website's URL.
