What powered sites? We are always curious about that when we navigating exciting sites. PoweredSites is an open site to share with others about a project or service powered sites, eg. jQuery powered sites, Python powered sites etc. PoweredSites is also a good place to show your project's power if you are project owners.
Description:this site alerts you about emails you don't get. You tell it what regular emails you should get from your automated systems, backups, virus pattern file updates cron jobs etc. etc. and it will receive them all, and tell you when and only when one doesn't turn up on time (or contains words indicating a problem)
if you get lots of emails from automated systems that you just shove in a folder without looking at them then this will help you spot the ones that are a problem - or don't turn up.
