Heeeeeeeeeeeeeelooo People!!
I Don't Think This Has Been Posted Yet [Could Use Confirmation] But I Couldn't Find One So Here It Is!
This Is For People Who Are Just Curious About BBCode, Because There Are Also Buttons That Do Most Of These Things 
Alright, For Bulletin Board Code You're Going To Use Some Lot'sa Brackets!! ( [ And ] )
The Basic Principal Is, Everything Between [SOMETHING] And [/SOMETHING] Gets Altered/Edited By What's In The "SOMETHING" part.
In This Tutorial There Are "Spaces" Inbetween The Brackets, That Is Because Else It Would Mess Up The Order System Of BBCode. If You Want To Use These Things, Make Sure You Type Everything BETWEEN THE BRACKETS Together.
Alright, The Basics !!
Code:
* [b] [/ b] for Bold text
* [i] [/ i] for Italic text
* [u] [/ u] for Underlined text
* [url= "https://www.TheActualUrl.net] [/ url]for a clickable Url
* [img] ImageUrl Here [/ img] for an Image 
Now Somewhat More Advanced Stuffs !!
Code:
* [color="ColorName"] I Used "Red" [/ color] For a Colored Text OR!!
* [color=#ColorHex] I Used #FF0055 [/ color] using a hex color
* [size=1-7] [/ size] to alter the TXTSIZE
*[FONT="Fontname"] [/ FONT] Changes The Font Of the Text
* [code ] [/ code] to Create A Code, Like You See Around This Piece Of Text
* [PHP ] [/ PHP] To Create A Code Field For Somewhat More Special Codes
Like Visual Basic/C#/C++ so that the code gets generated as a php code
(meaning it get's colors wich you'll understand if you write Visual/php stuff)
* [Qoute="NameOfQuoted" ] [/ Qoute] to quote someone
Here, A Quotation Of The First Reply Of This Thread =D

A Few Other Maybe-Usefull Codes!!
