I dont have a P2 Genie yet, so i thought, is it okay to delete P2's on computer, not in camera? I've heard that in digidal photography its not recommended, but whats about P2's?

As far as I know, it is best to format the card in the camera or if you have it a p2store, that's what I have always done with no problems. I have p2genie, and I have never used it to format either the cards or my p2store.

Look in the manual, it should say somthing about it.
