Google Spreadsheet Sharing

I haven’t played very much with Google Spreadsheets, yet, but I did share a test sheet with my co-workers, and it seems that I’ve given them automatic access to the beta test. So if anyone wants to have a peek, email me or leave me a comment (only gmail accounts work, though, so be sure you have one of those first [Update: I can get you one of those gmail accounts, too, if you need one. Just drop me a line or a comment]).
