After a recent security update for PHP-Fusion it was necessary also to update two files in the Extended Profile Infusion. Though the Infusion is still listed as Beta on http://www.phpfusion-mods.com, no issues have been reported and I give it here as Release Candidate. See the forum for more.
Please note: While activating new accounts I usually check them out. If I notice an account registered with a temporary email address it will be deleted.
