Upper right portion of your page is empty, the font is a bit small and maybe you can come up with a better icon for your categories.
Another thing I noticed was under United States you have cities listed but it's not a complete list. I would change it to the states. Just my opinion Attached is a text file with the state names....
Yea, I have thought of that too, but right now I do not have that option with this script really. I will try and get that added soon, because that would make things more organized. As far as adding the number of ads beside each category, I still have not made up me mind about doing that yet, but I will more and likely will once I have numbers worth mentioning.
