If you are not a native speaker of a language, it might be worthwhile to access hitchwiki.org using Firefox and download the dictionary from [[https://addons.mozilla.org/en-US/firefox/browse/type:3|Mozilla]] for the language in which you are writing your contribution, so that you can spell-check what you're typing. As for using UK or US spelling, I'd suggest to use US spelling, but feel free to voice your objections.
