I confess. I didn’t search for the answer hard enough. Now I know. In Getting Started, Getting Finished and Navigating, look in the column on the left, the 7th item down. It says SEARCH TOOLS! Easy enough!
I know it seems easy, but I was looking for a little bar at the top of the forum page. Kind of like the one that is on the YouTube home page.
And, even better, I have Herbert as my new friend who will really make things much easier. YAAH!
Have fun searching!
