I have added a Free Directory if you would like to share links and enhance pagerank you are welcome to submit a link to it or request for a new category that does not meet computer security:

Free Computer Security Directory (http://heapoverflow.com/directory/)
http://heapoverflow.com/f0rums/directory/
(http://heapoverflow.com/f0rums/directory/) (navbar link)

note: This is better to submit your links to the directory than the forum "shared-links" section because in the forum spider bots won't follow to your domain.
