Got the download folder back in the dock - but I can't find the pdf folder - when I search pdf in utilities it gives me every pdf on my computer, but I can't drag all those down there. Hmmm. But at least the downloads are back down there.
Are you searching in "Utilities"? Not the right place to look for it. Simply open up a Finder window, then in the Search box there (upper right hand corner) type in the name of the folder. -If you type in PDF it will bring up all your .PDF files, but if your sort by "type", then you should see the Folder - that is if "PDF" was part of the name of the folder.
OH! BUT WAIT!!!
DO THIS FIRST:Open a Finder window.
Search for: "About Stacks.pdf" (ignore the quotes)
That should bring up the PDF file that will tell you about Stacks and the default folders it creates.
