1) 3.5.4
2)

PHP Code:

switch($userinfo['field5'])
{
    case "Optometrist":    
        $userdata->set('usergroupid', 48);
    break;
} 


3) i mean, that user has been put into the correct group, but his posts are moderated and his custom title and rank do not show under his name. i'm not familiar with VB, but I am only assuming this is because he is still in limbo (not activated) and that's why all of these things are happening.
4) www.domainname.com if you are going to try and register, you can only choose "Group" sinec I'm testing that code you wrote for token55. I was going to add the other groups later if this worked.
