Wikitravel Manual of Style

The most important tip that I found in the Manual of Style page on Wikitravel was the page "Where you can stick it." I think I would find this very helpful if I knew of a place but was unsure of which category it goes in. This eliminates confusion or grey areas.
Another great tip is the "Wiki Markup" page. This is helpful to people like me, that don't know anything about formatting text. Wikitravel has their own markup, so it's extremely helpful that they list an easy 'how-to' graph with everything you need to know.
Another tip I found is "No advice from Captain Obvious." This is a helpful page because it reminds you not to make obvious remarks in your entries. This may not seem like an important tip, but I know that I might be compelled to add obvious statements if I'm unsure what else to put. If the contributor feels like 'when in doubt, add an obvious statement' they must resist. This page tells you what is "obvious" to the traveler and what isn't.
