Adding another feilds that behaves like categories

Feb 5, 2013 at 7:52 PM
I'm trying to code some custom features into a blog for the office. The material is very complex and navigation would be much simpler if there were two more feilds that behaved like categories with a different name (e.g Questions).

Obviously this is going to take more than copy/pasting some C# functions on the defalt page. Can anyone tell me where all I'll have to look to make this happen.

Any suggestions would be appreciated.
