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.
Please note that we don't really consider the purchase of real estate - even for vacation use - to be a "travel" activity. - Todd VerBeek 14:17, 6 June 2007 (EDT)
Also, please look at our guidelines for accommodations listings; they explain the format we prefer to use (rather than repeating the same phrase and URL over and over just to maybe improve your search-engine ranking), and our requirements about third-party booking services. - Todd VerBeek 14:51, 6 June 2007 (EDT)
And while you're reading, take a look at Wikitravel:external links, which explains the limitations on linking to external sources for information. In a nutshell: we provide a single link to the local official tourism agency, and individual links to the official web sites of specific attractions. We don't link to multiple general guides. - Todd VerBeek 14:53, 6 June 2007 (EDT)
