How do I show the Directory I created using Directory Plugin

Dear WPMUDEV:
I am finding that the instruction and the interface of the plug ins I have tried very difficult to understand. From the user stand point, most instructions and the way the plug ins are designed are not for easy implementation.

I am trying to use the directory plug in. I have imported taxonomies and added one listing but I am unable to see the "front end" or directory page. How do I show this?

I am currently using WPMU Nelo 2.1.7 theme right now.
The url is http://www.exanderson.com

http://exanderson.com/listing/netsolver/

I added this listing but the url does not show and I just dont understand how it works.
Help please
