To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Wikitravel:Help, or post a message in the travellers' pub.
Thanks for your contributions, but please see Wikitravel:Categories. Unlike Wikipedia we try to minimize use of categories and generally request that a discussion take place before categories are added to articles. If you think tagging continents is important feel free to start a discussion about it on Wikitravel talk:Categories. -- Ryan • (talk) • 11:00, 24 June 2010 (EDT)
