Dmoz (Open Directory Project)

Dmoz (www.dmoz.org) is a volunteer run directory that was created by Netscape and used by Google as its directory. In the early days of the Google revolution, Dmoz was one of the most important places to list your website in order to improve rankings in Google. Google placed a great deal of weighting on sites listed in this directory and it was therefore vital to have a listing in a keyword rich category. These days Google still uses Dmoz as its directory source (http://directory.google.com) but most experts agree, it does not place as much weighting on a presence in the directory as it once did.

I would advise that you submit your website to the most relevant category in the directory, and follow up every few months to make sure it has been accepted. The editors of each subject area are notoriously hard to budge, and they themselves admit, that it can take months for a website to be included in the Directory.
