Hi, I have submitted a patch that add a "unique value" setting/function to profile fields. If this is a feature you are interested in please have a look. http://drupal.org/node/74800 http://drupal.org/files/issues/profile_uniquevalue-2.patch The patch is used on a production site with Drupal 4.7 where this feature is needed and it seems to work as it should. I'm interested in hearing if the implementation is good and to make it part of core, making it easier to update the site.
