#14 On-Line Productivity

I use Google docs frequently. I have looked at Google's spreadsheet tool and I like the idea of different people going into a workbook, and adding data. Excel (as far as I can tell, I am far from expert) doesn't really allow for collaboration, just additions. Both of these tools are useful if you don't have or can't afford Microsoft and other expensive software, and it adds a collaborative function that is quite useful.
