Here are some suggestions and tips that I hope will help to keep our Life on Mars pages consistent and readable.
It seems logical to make UK English the spelling standard. This can be done most easily by setting it as the language in your word processor. In general, the areas to watch out for are, "centre" over "center"; "honour" over "honor", "realise" over "realize", "programme" over "program"; "dialogue" over "dialog"; "tyre" over "tire", etc. The only exception I would suggest is using double quotes rather than single because they are a little easier to see. A number of non-standard terms and pronunciation examples may merit "special treatment".
It's probably best to make the plot summaries fairly detailed, given that the series has been over for a while, and the "spoilers" issue is less important.
Follow the standard practice of writing in the present tense. At the first mention of characters' names, their full name and title should be given and a link to their page provided if they have one. Subsequent mentions can be more familiar and no link is needed. Please try to start a new paragraph for any significant new action, location, or other important topic. Do not be afraid to repeat the characters names to make descriptions clear, since that is better than confusion caused by too many pronouns.
This should be interpreted fairly broadly. Remember, not only are the references over thirty years old, but, with a world-wide audience, not every viewer can be expected to get all the British references. A complete history of the item is not always necessary, but you should aim to give the significance of the reference in 1973–74 and in 2006. This helps the reader understand the reference both from Sam's perpective and from the perspective of those native to 1973.
Make the paragraph in bulletted list format. Introduce each issue with a short explanation to give the context. The first appearance of the word or phrase being explained should be bold. If using a quote that is integral to your sentence, a comma precedes the quote, the first word of the quote is not capitalised, and any final punctuation goes inside the final quote: Gene says, "shut up!" A quote within a quote uses single quotes.
