I want to make it longer before vbulletin refreshes who online to make it look as if more people are on. I went into the who's online setting and change the Who's Online Refresh Period to 2147483647 but it still refreshes every 10 min what am I missing?
You've got the who is online confused with the session timeout. What you need to do it up the timing here: AdminCP -> Cookies and HTTP Header Options -> Session Timeout This changes the timing of when vBulletin checks to see if someone has dropped offline so to remove them from the current online users list.
