When you visit any forum, you'll see a "search forums" box at the
top of the forum. Enter one or more keywords and do a search. Go
through the results and click the "advanced search" link under the
"search forums" box if you wish to refine your search. If your
keywords don't show any results, you'll see a form to do an
advanced search. In general, start with one or two simple keywords
and then refine your search if you get too many results.
