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.
If you have marked a page as "watched", the last contribution to the page should appear when you view the "my watchlist" page at the top of the screen when you are logged in. If you want to see ALL of the edits on a page (in case the last edit was not the only edit made to the page), you can go to the page and click the "history" icon. There, you can look at every revision that has been made to the page. These are the best ways to keep an eye on pages that you don't want to see vandalized. If any of this is unclear, feel free to message me again. ChubbyWimbus 21:49, 3 August 2009 (EDT)
