i tried to submit my site to dmoz but its highly not giving the main addlink page if i clik on that something is displaying pls help me out
syted has given you as much information as you need to suggest your site, so I'm not sure what more I can say, except to rephrase the instructions. Find one category which covers a topic as close as possible to the topic of your site, and accepts site suggestions. Then suggest your site there, once. When an editor finds your suggestion, they can easily move it to another category if necessary. We do that all the time.
Start from http://www.dmoz.org Choose a category and subcategory according to your niche. Go to suggest url link just above the search button. ... and you will get what you are looking for.
just travel through the right catagory you need and sub catagories your site fits in, when you think that your catagory and sub catagory has arrived, just see above you will find a link "suggest url" click it and you are on the go.
