It is not difficult at all.
In the Board Statistics box at the bottom of the Forums, and under the colour code information, you will find:
QUOTE
Show detailed by:last click, member name.
Clicking on member name will initially only show what BC Members are doing (you can change that to "show all users"); Clicking on last click defaults to all users sorted by most recent clicks. You can change one view to the other by changing the first sort box. A browser "refresh" is needed to update to current usage.
Something similar shows when you are viewing a forum thread. At the bottom of the screen you can tell how many people are reading the topic and the names of any Members viewing it.
Regards,
John
