There is none, as far as I know. I have been requesting this since early in Beta days. The problem is, I never seem to guess right about what category a given sub-category is in. They do not divide it up the way I would, that's for sure.

P.S. I give up: where IS the senior citizens category?

All the categories cant come out at the same time cos its quite much, so you may have to click more than once.

Look for categories at the left side of your page.

I could never find any either!!! Can be frustrating....It's be a GREAT suggestion to give to yahoo answers!!! Hope to see them add the feature in the near future!

Thanks for bringing it up!

They are all listed over to your left.

I guess they are trying to make yahoo answers much more organised incase some people only want to answer certain question, or are knowledgable in certain areas.

sorry i misunderstood your question, you can find this to the left of the screen
