If you are seeing this thread, I’m no longer with you. I’m making this thread as a guide for future forum users who may not know how to properly use and format their posts. I know there are a lot of tech savvy people here but I imagine there are many who don’t know how to format their posts using code. Since you can use Markdown, BBCode, \LaTeX and HTML, there is more than one way to format your text and this can get confusing.
Anything you need is most likely in one of the helpful links below but I decided to type everything out because… well, I don’t know why but I’m doing it sooo, 
yeah. Anyways, this is a wiki so feel free to add your knowledge since I’m tired of typing and have a bunch of reviews to do.
Some text might not output as expected, including ¯_(ツ)/¯ ¯_(ツ)/¯ (A solution: ¯\_(ツ)_/¯ ¯\_(ツ)_/¯) - be sure to learn.
Also, be careful of anything that between <TAG_NAME> and </TAG_NAME> (see, Markdown inside HTML section).
Technical details
WaniKani Community is a Discourse forum, using markdown-it as the Markdown parser, although there are several extensions (e.g. BBCode-like, MathJax).
The GUI (Text Box)
- Speech Bubble: When you reply to a post, clicking this will copy the entire post and add it as a quote to your post.
- B: Bolds the selected text.
- I: Italicizes the text.
- Chain/Link: Adds a link to the entered website.
- ": Adds a block quote to your post.
Is this important?
- </>: Allows you to type anything, including code, without changing it to that format.
<sup>This is not small :disappointed: </sup> - Image: Hopefully you know how to use this.
- Bullet/Number Lists: ^^ Same.
: ^^ Same.
Settings:- Hide Details: This creates an open/close drop down like >The Gui (Text Box).
- Insert Date: Insert a time that shows based on each person’s time zone. I never even knew this was a thing.
- Blur Spoiler: Adds a film to the text that disappears after clicked.
Just because you see this doesn’t mean it’s really here.
- Build Poll: Shout out to the POLL thread Woot! Woot! Builds a poll based on what you choose. Go crazy.
And that concludes our tutorial for the post GUI. Stay tuned for how to edit and add your own special something somethings. 
Formatting
If you don’t want to use the GUI or just want to keep typing, this is the place for you.
Italic:
[i]purple[/i]purple_blue_blue*red*red- Ctrl + I
Bold:
[b]broccoli[/b]broccoli__kale__kale**carrots**carrots- Ctrl + B
Strikethrough:
[s]potato[/s]potato~~potato~~potato
Super/Subscript:
<sup> tiny north </sup>tiny north<small> tiny neutral </small>tiny neutral<sub> tiny south </sub>tiny south<big> anti tiny </big>anti tiny
Underscore:
[u]Amazeballs[/u]Amazeballs
Highlights:
<ins>green</ins>green<del>red</del>red
Bullet Points:
* What's your point?- A dash.+ Is that 十 Koichi?1. I'm number one!
Block:
I like eggs.
Pre-formatted:
One-eyed, **one-horned**[code]One-eyed, **one-horned**, flyin' purple people eater[/code]-One-eyed, **one-horned**, flyin' purple people eater
Nonetheless, you can format on over pre-formatted - One-eyed, **one-horned**
Pre-formatted block:
<pre>Preformatted _text_ :thinking:</pre>-Preformatted text
It breaks into a new line by itself, even though in raw in on the same line.
Aardvarks
_Porcupine_
"A polar bear's head"
Note: These are backticks (the key with the ~) and not a single quote)
```html does not work
Compare
<ruby>some<rp>(</rp><rt>furi</rt>)</rp> kanji<rp>(</rp><rt>gana</rt><rp>)</rp></ruby>
and
<ruby>some<rp>(</rp><rt>furi</rt>)</rp> kanji<rp>(</rp><rt>gana</rt><rp>)</rp></ruby>
```
Aardvarks
_Porcupine_
"A polar bear's head"
```
Another way to block quote - 4 spaces are needed in the front:
More **Porcupine**
"I love polar bear's head"
Line Break:

Table:
Option #1 (harder)
These tags are nested within each other. Each table must have the table tags as the first and last items.
The tr is equal to a row in the table. For each row only one set of tags in needed.
td are column cells. These go inside the row tags and there can be as many as you need (within reason).
th are header cells. Use these instead of td if you want.
<table></table><tr></tr><td></td><th></th>
<table>
<tr><th> Cats </th><th> vs.</th><th>Dogs</th></tr>
<tr><td>X</td><td>O</td><td>X</td></tr>
<tr><td>O</td><td>O</td><td>-</td></tr>
<tr><td>X</td><td>O</td><td>X</td></tr>
</table>
| Cats | vs. | Dogs |
|---|---|---|
| X | O | X |
| O | O | - |
| X | O | X |
Option #2 (not not easier)
| Kanji | Meaning | Reading |
| - | - | - |
| 1. 一 | Loneliest Number | むし |
| 2. 二 | First Loser | かかす |
| 3. 三 | Without Serif | やま |
| 4. 四 | The Force | ほし |
| Kanji | Meaning | Reading |
|---|---|---|
| 1. 一 | Loneliest Number | むし |
| 2. 二 | First Loser | かかす |
| 3. 三 | Without Serif | やま |
| 4. 四 | The Force | ほし |
Option #2 with Column Alignment
You can align columns by adding colons to the separator line:
| Left Kanji | Centered Meaning | Right Reading |
| :- | :-: | -: |
| 1. 一 | Loneliest Number | むし |
| 2. 二 | First Loser | かかす |
| 3. 三 | Without Serif | やま |
| 4. 四 | The Force | ほし |
| Left Kanji | Centered Meaning | Right Reading |
|---|---|---|
| 1. 一 | Loneliest Number | むし |
| 2. 二 | First Loser | かかす |
| 3. 三 | Without Serif | やま |
| 4. 四 | The Force | ほし |
Mathemathics ($\LaTeX$ / MathJax)
I put LaTeX in a separated thread, because it cannot be hidden inside [details].

Markdown inside HTML
Standard way to put Markdown inside HTML is, 0ne blank line after the last tag.
More than that being discussed here..
Nonetheless, several tags already support Markdown inside HTML by default.
<span lang="zh-TW">**誤解**</span>
<span class="spoiler">**Another spoiler style** is not broken.</spoiler>
<ruby lang="zh-TW">**誤解**<rt>~~にゃにー~~</rt></ruby>
<small>**誤解**</small>
誤解
Another spoiler style is not broken.
