Instead of Prue-Phoebe-Piper? Maybe this has to due with the fact that Rose McGowan was on the show longer than Shannen Doherty. Heck in the profile photo for this forum, it's Rose in the picture instead of Shannen. To make matters worse, the producers once Shannen was off the show, couldn't show footage or images of Prue since I believe Shannen denied them permission (if she didn't get a hefty payday). This is why it took much longer for the first three seasons to be released on DVD.
