Why I can't submit long time?

I tried sibmit to http://dmoz.org/Computers/Software/Shareware/Windows/Internet/Clients/WWW/Browsers/Add-ons/

my site -- www.adscleaner.com which is related to this category.
I tried to do it many times but unsucessfully.

Who is responsible person? In this and in parent categories any edotors are absent.

What I must do?

You should go to the Site Submission Status forum, read the important guidelines in the very first post, and post a properly formatted status request.
