Here in this world, Web Directories are very common. there are more then hundred thousands web directories known at present and they still growing day by day.
So This is one more Directory that I really like B5U.org . This is a one of the fastest emerging " free Web Directory ". Known as Umer's Free Web Director . Here you can submit as many links as you want and You don't need to pay anything in return of this.
In this site, you find many categories where you go and then submit your site in most relevent category very easily. This Directory is updated regularly and if you leave regular link then It is approved within 1 month. but this directory also have a way to submit your links faster if you buy feature link, it is approved in max 2 days.
