This category lists sites with tutorials related to web programming which uses the Common Gateway Interface (CGI). The tutorials can cover every language, for example CGI programming with Perl, Java, C/C++ etc.
Please only submit your site if it contains real content related to CGI programming. If your site only contains a bunch of links to sites related to CGI, this is only more confusing for visitors to find the information they searched for.
In my opinion deep linking is allowed: If your site is already listed in some category in the Open Directory and you also have a few tutorial pages, you can submit these pages to this category for listing.
