Gentlemen, I assure you that the reasons some may change their username is not to hide their identity due to doing something wrong here in the past nor becuase they are a nut case (haheha). Some may change their name because of lack of respect or lack of responses when posting, for example, I posted "All time favorite arrangers" because I was interested in knowing everyones opinions since I never owned any besides the PA80. I only got 6 reponses. Fran posted "recapping our arranger list" and got 48 responses. Things like this make you say to yourself, what gives??? So, some may feel that they aren't part og the in crowd and try switching their name.
