how do i get the topics of my forum to display on my webpage?

you mean; you want to use the forum main page as the index page?

if your server supports SSI put this code in a blank text file and save it as index.html or index.shtml (or what you server supports...);

<!--#exec cgi="cgi-bin/ultimatebb.cgi"-->

why not if u want the front page as the index just use a redirect script
