Okay, how many of us have reinstalled mozilla (or NS4.x for that matter) or made some other change, where you start up Mail and your previous mail and news accounts don't show up any more? I've seen quite a few posts with confused questions about this, and I have experienced it myself.
Right now, I know that prefs.js contains a lot of information about your various accounts, and I have three folders: ImapMail, Mail, and News. It would be great if the appropriate prefs.js for each of my accounts were spread out into files in each of these directories. That way, I could take my News folder and copy it to another profile directory. Then mozilla would start up with that profile, see news, get the prefs from the news directory, and load it appropriately. This kind of behavior would be so much better than the way NS4.x and Mozilla determine your mail settings (which seems to involve voodoo sometimes). It would also be nice to be able to nuke my prefs (for troubleshooting purposes) without endangering all of my messages. I just wanted to post this here before filing a bug to get opinions.
