I Strongly advise you to upgrade, 6.2.1 is old and there have been many enhancements made since then. Also I suggest you edit the template for your search if you do not upgrade, to stop people from searching all forums at once. A simple code mod can limit it to members only. You can do this with WOL also, or make the summary Admins only, to reduce it more. I've doen this for several of my clients in the same situation.
