Go to goggle, put in your search terms followed by site:forum.cakewalk.com
So your search would look something like this:
sonitus delay reverb vocals site:forum.cakewalk.com
I've given up on using any forum's search engine; google gives much better results and you don't have to wait a minimum time (as is imposed on some forums) to search again.
Of course, I have no idea if the article you're looking for will come up. I did a search this way, but nothing jumped out at me as obviously being what you were looking for.
