OK so I am a memeber of another forum that uses this same software. The "Forum Jump" box dissapeared over there as well. I inquired and was promptly responded to by one of the admins with this:
damn...i was wondering if anyone would notice that....the admin panel said to disable the quick jump to improve "speed" so i tried it.....lol
The forum jump menu ads another 2 queries to the database for every user, therefore if we have 740 users online at one time that makes an extra 1480 queries per second. I used to use the forum jump menu as well but for the sake of speed I had to remove it.
