One more method is to use a redirector META tag in /forums/index.html that automatically redirects you to the Ultimate.cgi file.
Yet another method is to simply install your .CGI files into a "/forums" directory. Then use .HTACCESS and set the Index file of that directory to Ultimate.cgi. Then whenever a user goes to your.site/forums/, Ultimate.cgi will display. Unfortunately, I don't know the exact .HTACCESS code to do this, but I know it can be, and has been, done. If anyone is more familiar with .HTACCESS, you might see if they can help.
