Have never used PHPFox so no idea what its database looks like or how files are stored using it.
If it was possible for me to take a look around a PHPFox back-end I could maybe assess things.
Its unlikely that we'll automatically save actual (non-encrypted) user passwords as that compromises all of Jamroom and user security. Here at Jamroom, if we need to login as a user in order to support our code, we just ask the user for the password.
Do you actually need to login as your user? As a Master (or profile) admin when viewing a profile page you effectively take on that profile's identity and can see all his items, posts etc.
