macwise or Trent,

Would you mind writing a few lines on how this actually works? I have two main questions:

First, I’m intrigued by the call to “apply_filters()”. Does this make it possible for future plugins to use “ra_get_wp_profile_info_keys” as a hook? In other words, the plugin would achieve the same result if it just returned the second argument of “ra_get_wp_profile_info_keys”: “array(‘user_email’… etc.”

Second, how and when does a new column get added to the database for the custom profile fields?

Just curious, and learning about plugin development.

Thanks.
