I have been digging around in 6.4 to change the time on the Who's Online page from the default 10 minutes. Anyone have an idea of where I can do this. TIA.

In your config settings under Special Functions / Misc. settings

Well, they certainly made that easy didn't they? Thanks DL. Also, did anyone else get the "onfire" topic image in all threads regardless of whether there is any replies or not?

Edit: Found it.

You need to set an amount for number of views / number of replies in the config file. If it's at 0 then every thread will qualify as a Hot topic.
