Hey giantstogie... I run it via cron on a linux web host I have (don't tell my host i'm doing that, LOL). If you have a linux/unix host you can run it on, I can email you the script, or if you PM me your email address, I can just add your addy to the alert if you want.
Kyle, if you want me to add your email to that as well, just PM me your email address and I'll get you on there as well.
I'll also note that I think there is some caching going on that I need to get around... I continued to get false alerts for about an hour or so before it stopped sending the alert. I think I know a way around that, but I don't have a handy way to test it.
