Just learned that there don’t seem to be current plugins that allow multiple user accounts 🙁 Ughh…this is awful!

I’m thinking to use Formidable Forms for the user registration, and they offer this as an option:

Don’t require a unique email#
This can be used alongside a plugin that allows multiple user accounts to be registered to the same email address. This will remove the error added to the email field for a non-unique email address. Replace 50 with the ID of your Email Address field.

add_filter( 'frm_validate_field_entry', 'remove_email_error', 25, 3 );
function remove_email_error( $errors, $field, $value ) {
    $email_field_id = 50;
    if ( $field->id == $email_field_id && isset( $errors[ 'field'. $field->id ] ) && $errors['field'. $field->id] == 'This email address is already registered.' ) {
      unset( $errors['field'. $field->id] );
    }
  return $errors;
}

So I’m just curious if this would work with Buddypress.
