I just became one of the first people offering personalized, expert help over live video through a new Google product called Helpouts. The main page for Google Helpouts is helpouts.google.com, and my Excel listing is at bit.ly/ExcelBob
With Helpouts, you can get help when you need it. I can help you with features like formulas, functions, creating workbooks, making charts, importing & exporting data, and more. There are other people using Helpouts to offer their expertise in other applications and non-computer topics also, like household repairs, playing musical instruments, speaking foreign languages, and more.
To use a Helpout, all you need is a computer, smartphone or tablet with a camera.
