I need help with categories, and the FAQ for wordpress is singularly uninteresting.  I was playing around with my categories and the “category parent” feature trying to figure out what it did.  I still don’t know what it does but I managed to lose half of my categories?

 I hoped it would create some sort of hierarchy – so I could choose the category “knitting” and then the category “socks”, for example – but that does not seem to be the case.

 Anyone have any fantastic category/sorting ideas?

 Thanks!
