Category selection and guiding people to pick a category

[LIFE]

Hey, I think it would be a good idea to by default set the "category" box to N/A, then direct the poster to pick a posting category instead of defaulting to suggestions. Right now the suggestion tab since it is default and people dont know they need to change is a defacto "general section" instead of a suggestions section.

Not too big a deal, but a good idea nonetheless
