Style Guide
I figured I should make a style guide so if you want to edit but are feeling unconfident about doing it right you simply can.
FIRST OF ALL. None of these are hard and fast rules, and any of them can be changed as needed. Do whatever!
Formatting
For proper wiki styling, proper capitalization and grammar as well as full sentences is recommended, except for where breaking from this would be funny or provide emphasis. I make sure that the first time the thing the page is about is mentioned in a paragraph, it's by name (e.g. "Weatherman is..." rather than "He is...")
The first time that another thing that has a wiki page is mentioned on the page, provide a link to the appropriate page by putting square brackets around the thing mentioned. Sometimes I also do that link again when that something is mentioned again, if the first time wasn't obvious or intuitive enough.
I try to maintain a formal, wiki-able tone, but also try to include funny bits where possible, especially bits where the humour comes from completely deadpan including some bizarre nonsequitur. oh yeah space florida we've all heard of it. refuses to elaborate. leaves.
Fighter Pages

Once we get infoboxes to exist, the first thing on each fighter's page will probably be their infobox. For now, if you have their official smash render, put that right at the start of their page so that it's not below any of the lines of text; I format them like [[File:Planos.png|thumb|right|200px|Planos's render.]], which makes them contained in a little white box, on the right side of the page, 200 pixels big rather than massive, and gives them an accurate caption.
The information I try to have on the first line of each page is the fighter's name and any aliases (which I put in bold; I think most wikis do so by linking to the page you are currently on instead of using html bold tags, but whatever), what team they are on, and what smash fighter and skin they are represented by, usually also revealing a pronoun while doing so.
Generally the rest of the page is then their blurb from their submission form and any other information I have about them.
If there are any notable quotes from or about this fighter or that could be construed as such, I put them in a blockquote, usually italicize them, and then put a dash and whoever said it inside the blockquote but not italicized. E.g. <blockquote><i>"I killed a man in '09!"</i> -Neopet</blockquote>, which will look like
"I killed a man in '09!" -Neopet
At the bottom of the page, I put their team's navbox and the tags for whichever categories are appropriate (usually Fighters and their team, but if there's another notable group they're in, also that; feel free to make a category on the spot if there are a bunch of pages that should be grouped together). E.g. {{AnnouncersNavbox}} [[Category:Fighters]] [[Category:TeamAnnouncers]] (except I put these on separate lines when I'm actually doing a page).
