I found a small bug in forum_configure.asp
at line 303 is the raidio button for blnActiveUsers That decides which one will be checked in Active Users List when the page is loaded. well the bug is the next set of raidio buttons control the Display Moderator Groups on Main Page: and it uses the same value blnActiveUsers
If you have Active Users List turned on and Display Moderator is turned off it will look like its turned on anyway so you have to change that raidio button every time you hit the page.
