Need vbulletin & aweber integration

Hey people, I need a plugin for vbulletin 3.8x that makes anyone who registers at a vbulletin forum get automatically added to my aweber list. Please note, it must work for single opt-ins at aweber. I already have a plugin for vbulletin that adds people to my aweber list, but they have to still double opt in. I need a plugin that works for single opt in. You must have your own copy of vbulletin to test the plugin, as I can't provide you admin access to mine. Thanks!
