Wikitravel:Manual of style
Our Manual of style is a collection of rules of thumb and guidelines for giving Wikitravel a consistent look and feel. Most of these rules have exceptions, but to put together a good reference work collaboratively, it's best to follow the rules unless they're quite inappropriate for a particular situation.
The Manual is broken up into different pages so that this one doesn't get overloaded with extraneous text. It makes it easier to find and update individual rules or concepts if they're on their own pages. Finally, it's easier for smarty-pantses to link to the particular rule being broken from talk pages for articles.
If all this stuff makes your head swim, and you don't want to bother with it, by all means plunge forward and just start sharing your knowledge. Other Wikitravellers will come through and bring your contributions more in line with the style guide.
If you have a question about the specifics of the Manual, or want to see it changed/amended/clarified, use the talk page for the section in question. A list of issues currently being discussed can be found here.
These rules are about laying out individual articles. That is, they describe how we take raw information and put it in a format that's easily usable by travelers.
This set of rules describes how to write words, sentences, and paragraphs.
