Converting Visitor to Member

'session_started' only fires once in the flow of loading a URL.
Maybe if you have some ajax on the page and are opening several URL's on a single page, that could cause it perhaps.
You could set a flag or a cookie or a session variable to prevent multiple whatever-you-want-to-do's happening per visit.
There's the 'router_init' event in router.php right after the session_init in flow of things. or 'parse_url' is just before the session start stuff.
