Welcome to the wiki
Hello, and welcome to the explain xkcd wiki. Please, do not create explanation pages without an explanation. We are not here to mirror xkcd. We are here to explain the content of the comic for those who might not understand the jokes, so by creating a page without an explanation you are simply mirroring xkcd and stealing pageviews from there. That would be rude.
Also, explanations go on a page titled as "comic_number: comic_title". The List of all comics has a helpful create link to assist in the creation of the page. We reserve the comic number, and the comic title pages to be redirects to the explanation page, this way each explanation will have its own page without a naming conflict, and any of the redirects can become disambiguation pages (as has been done with Exoplanets).
