Rename Child Boards

[Heartlander]

I did this on another site, but can't remember where the file is to change the name "Child Boards".

I mean "Subforums", or anything is better than that term as it is displayed.
Any help is greatly appreciated.

You'll need to change the relevant language string. See the language string link in my signature for the actual file and string that you'll need to edit
