The reason why I'm aiming for the session hook is because the session is only called when the session timer has elapsed, thus the php plugin would only be called for once every xx min/hours depending on the session settings I would use. Thus less queries in the end, rather than being called every single time the user browses the forums with, eg global_setup_complete.

If you have any other good hook or php code that only runs on the user eg, once per specified hours.. that'll be awesome. Though only when the user is browsing the forums.
