Signing your posts on talk pages prevents readers from getting your messages confused with those by other users. Also, it is considered proper "Wikiquette" (WI-kee-ket) to sign your messages. To do this, type four tildes (~~~~) at the end of your comments. When you save the page, these will be converted to your signature followed by a date stamp.
