If you still use Yahoo Groups, get ready to save your stuff. Yahoo will remove all content on the discussion board site on Dec. 14.

The change was quietly mentioned on a Yahoo Help page. "As of December 14 all previously posted content on the site will be permanently removed," it reads.

I found the info on the PC magazine website. You can read it here.
