Another way you can go is to create your own templates. You can base these around the types of articles you enjoy or you can visit other directories to see if you can find a general idea that gives you the ability to come up with your own template. Using your own articles may help you come up with your own templates as well. If your articles are along the same lines, you should be able to come up with a number of templates.

The navigation menus have to be bold and attractive to the visitors. The overall site needs to be user_friendly.
