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
I use headings as needed, such as if there is a relevant subcategory of information. I also consistently use headings if there is any trivia, or any images other than the render (or that do not have an obvious place to slot into the rest of the page to highlight a point). To create a heading, on a new line put something like ==Gallery==. You can create increasing levels of subheadings by adding more equals signs.
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).
Images
Images are good. Use a lot of them. When uploading images, I usually try to make the name of the image clear and easy to remember/as intuitive as possible (e.g. all the fighters' renders are just their names, without spaces and generally with a capital letter at the start of each word), but for images that are people's art, if there's already a name I haven't been changing it so some of them have complicated names. For images that are people's art I do, however, put the artist's name at the start of the image name.
When creating a gallery, eventually I'll implement a gallery extension to make it look good but for now we still have to do it manually. For the prettiest style of having several images, make all of them thumbnails (this also helps to display artist credit) and, if you have at least 3, write them in order of left-right-centre because otherwise they don't wind up on the same line. This will look something like [[File:Cinnabar.png|thumb|left|image 1]][[File:Citrine.png|thumb|right|image 2]][[File:Copper.png|thumb|centre|image 3]] which will look like:
Note that this currently means that the images will not be in the order that you write them down, so be mindful of that.
Also uhhh I'm not sure why the text above did that (partially centred) or how to fix it. So be mindful of that.
