Here are couple things that might help you when trying to add some general data to the category page. If you want to add a lot of information i would encourage you to create a free-space page.
On a category page (or profile page ) to create a bulleted list add a * at the beginning of each line, to just indent the line use a colon, or to do an indented bulleted list use :* at the beginning of each line. (For numbered lists swap the * for a #.)
As for adding links there is a nice clean way to do that as well. Use the following format: [URL Title]. So you use one "[", copy in the URL for the site directly, insert a space, type a title for the link, and then add the closing "]". For example [www.wikitree.com World's Family Tree] would display World's Family Tree as a clickable link to the site you specified.
Those maps would be cool for the counties but you have to think about the role of categories - which I am still trying to process. Think of categories as more of a road map directing you to things. You will have some general information about roads, cities, parks, etc. included on the map but generally the map is just to help you get from one point to another. A profile or in this case a Free Space page is like an encylclopedia entry or some other data source. It is where you would go to get detailed information about the place and things related to it. That is why I mentioned previously to just include a little context information on the category page as it's purpose is not really to provide detailed information but to provide direction. I think it would be wonderful for people as they have time and interest to create free-space profiles for the counties that include the maps you are talking about and other pertinent genealogical data and links.
Let me know if this makes sense or not. Great thoughts and suggestions by the way.
