We do not discuss specific URL's on this forum. The most probable reasons a listable site hasn't been added is that a volunteer editor hasn't reviewed it yet. The listing criteria can be found here:
http://dmoz.org/guidelines/include.html
If the site meets the criteria for inclusion and it hasn't been listed most likely no one has reviewed it yet.
Public suggestions are one small resource that editors use to find and add sites and some categories they are generally a poor resource at best. If you have suggested your site there is nothing more that needs to be done, a volunteer editor will eventually find the suggestion and act appropriately.
