 * Helo, I am using an outdated mod called wordpress united. I have managed to keep
   it working until the new version 3.3.1. Unfortunately, something with the new
   version of wordpress has created a new error for me. The mod itself is based 
   on phpbb, but it was something with wordpress that messed it up. So, before going
   back to the previous version, I was just wondering if it is possible to fix it.
 * The main problem is that I cannot edit user’s information in wordpress. I get
   error after hitting edit on the uers profile page in the wordpress admin area:
 * `Fatal error: Call to undefined function email_exists() in wordpress/wp-admin/
   includes/user.php on line 173`
 * Unfortunately, I had to rename email_exists() to email_exists2() to ge the mod
   to work. This was not a problem with 3.2, so I am wondering what changed to create
   this error.
 * I appreciate any help. Thank you. Also, if you don’t think anything will fix 
   it please let me know how one goes about downgrading to the previous version.
   Thank you.
