Other ways to know who's working
Well I actually email it to myself and open it in an email from the browser which requires me to log in with password. It would be the same as coming to this site and getting the numbers from the ads myself or having them just in my phone book as friends. No where on there does it have any hobby related stuff. Just names and numbers in 4 different columns. Only difference is that the SO can not get to the spreadsheet but she does like to look through my phonebook.
Try the SNATCH thread in ISO's, it's the best for short notice and cancelations.
