When I went to do a search, it had this thing "Also search in child forums"

What exactly is this?:)

I don't think that Knitting Help has any, but some forums have related forums within the broader forum category. For example, if you came into "General Knitting" and there was a forum in here called "Acrylic Knitting And You", that would be a child forum. :)

Okay, Thanks!

Yeah, it's a sub-forum of the main one.
