Category List

Is it possible to use a drop-down list for category?
I think it's would easier to use.

I'm not sure what you mean here, perhaps you could be more specific. It might help if you have the URL of a page that you think could be improved, and then describe what you would change to improve it.

But be aware that changes to the dmoz.org page layout and interface can only be made by AOL staff. And they seem to have a rather busy schedule already.
