Just found Pandora Mail and I'm over the moon. Been with Eudora for 20 years and the time has come... what with unicode and certificates. A question: It seems that if i change the main mail folder from C:\username\appdata\ roaming\pandora\mail to another drive, it does not move the already established folders, just begins again from scratch? Could I manually copy them over to the new folder on say D:\ drive to maintain all the older mail? thx
