@sunandmoon,
I cant believe anyone here on this forum would criticize anyone for anything! LOL We are all here because we all have had a problem with calling to many psychics, or we have been scammed by so called psychics. I have yet to read one post from anyone saying they have never spent to much money on psychics, they have only had great experiences, everything worked out just like they were told, or they remember every last detail of a reading! So whomever criticized you really is angry with his/herself.
I love the spreadsheet idea, it is organized, dated, and easy to really see who is accurate an who is full of it. In addition you are probably able to calculate a percent of accuracy based on the results of the spreadsheet. I love your idea, its a very good idea, so forget whomever is jealous they didnt think of it, and ROCK IT!
