I'd like to export a list of the users and their emails from a specific group. Is there a way to do this? And if not, is there a way to export all users, but add more fields to the list besides username and email address?
My best guess is that between .6 and .7, we made the decision to only show a certain set of profile settings. Prior to this change, any plugin could save any data into the user's account hash, which was a potential security vulnerability.
Now, you'll have to register a listener to filter:user.updateProfile, and append the field you want to save.
