I discovered your site about 5 months ago and use is everytime i hit a hurdle in Excel or need creative graphing ideas. Because of your site my bosses consider me our teams Excel expert. I think what makes this site the best resource for intermediate Excel users like me is that you explain everything simply and in a stepwise fashion and then you make available the ground covered in an Excel file which i can save and against which i can compare my own interpretation of the tip using my own data. I guess that’s just a long way of saying thanks a mil, man!
