We only accept Open Source related sites. We care a lot about the quality of the Oslookup Directory. We don't accept all sites due to we aren't a general search engine, so please don't take it personally should your site not be accepted. Our goal is to make the open-source directory as useful as possible for all community, not to have the directory include all (or even most) of the sites that could possibly be listed.
Just type http://www.yoursite.com in the search box and click SEARCH, to ensure your site isn't already listed on Oslookup.org. This saves everyone time.
Identify the best category for your site. You should submit a site to the single most relevant category. Sites submitted to inappropriate or unrelated categories may be rejected or removed.
