I was coming back to edit this and I see that Suze already mentioned them in her comment. There is an extremely useful website called Paper Playful (Used to Be Feline Playful) that lists dozens of challenges of all types. It is a great jumping off point to start you on your challenge journey or for even seasoned carders to refer to for what's happening out in the world of challenges. The wonderful ladies who own the site work extremely hard to put this site together. I thank them for the up-to-the-minute information they give to us for free!
