why are some links red? What are the ? links?
They both indicate that a page with that name has not yet been started. Which one you see depends on your Special:Preferences. If you have “Highlight links to empty topics” checked, you’ll see red links. Otherwise, you get the little blue question marks. Either way, you can click on that link and start a page with that name. But be careful — there may already be articles on similar topics, or an article on the same topic under a different name. It’s pretty important to hunt around for similar topics first. See Naming Conventions for information on naming pages.
