Adding to settings

[Stv]

I'm trying to add on option to the settings under the 'House Rules' heading, but I'm failing miserably.
I can add under 'client' 'game' and 'combat' no problem. I just can't find/figure out the label name to use for the house rules.
Can anybody help me out?

Thanks, Steve.

**EDIT**
Just after I posted this, I found the correct text to use 'houserule'... simple when you know how :)
