Chandoo, I know what you are feeling, a few years back we had a severe power outage that lasted 2 weeks.

I also wanted to say that what you are doing in just incredible; the information you provide (and others) has been great for my presentations.

A question; how can I promote functional dashboards created in Excel to the Web, powerpoint, Sharepoint; etc.

Thanks again.
