I know there is a cache time, set in the Control Panel, General, Primary, Who's Online:
Who's Online Timeframe: Users will be listed as online if they have visited within this timeframe (in minutes).
What is the cache time set on this board -- My presence seems to show up sooner than on my board. My cache time is set to 5 minutes. Is it ok to set it shorter?
And then, how soon do people drop off the list? Are they taken out if they have not clicked anything for the number of minutes in the cache time? That wouldn't make sense if you cached every minute.
Thanks!
