I dunno if this already existed; lemme know if it did. The goal of this is to provide an easy-to-follow guide for players who are having technical difficulties.

"projectx.log"? What's that?
projectx.log is a file automatically generated by Spiral Knights whenever it runs. If you have technical difficulties, they can usually be traced by looking at this file. No, the file does not contain your login info; just info on what Spiral Knights did when it last ran.

Locating projectx.log
The required steps are HIGHLY dependent on your system. If you're already comfortable working with files, all you need to know is that projectx.log is in the same folder as the Spiral Knights executable. If you don't know what I'm talking about, read on...

• If you use Steam, right click on Spiral Knights from your list of games, and click "Properties". From there, go to the "Local Files" tab. The first button should say "Browse Local Files..."; click it and you'll see the Spiral Knights' root folder. Look through that long list of files for something called "projectx.log". Once you find it, open it in notepad or something, and copy ALL the text and paste them into a new post in your thread.
• If you use Windows but not Steam, you'll want to follow this. (If you are using Windows 10 and Spiral Knights is pinned to your taskbar, you want to right click on the Spiral Knights icon, and then on "Spiral Knights", and then "Properties".) Once you're in the Spiral Knights folder, look through that long list of files for something called "projectx.log". Once you find it, open it in notepad or something, and copy ALL the text and paste them into a new post in your thread.
• If you use a Mac, "On a Mac, find the Spiral Knights application. Control-click or right-click on it, to pop up a menu. In that menu, choose "Show Package Contents". (All Mac applications are actually "bundles", meaning directories filled with various kinds of executable, data, and meta-data files.) Then drill into Contents/Resources/Java/. You'll find projectx.log." (Bopp, 2016)
• If you use Linux, Spiral Knights is probably installed in your home directory. Open your home folder in some folder-manager (like Thunar) or in a terminal (like Konsole), and then go to the folder called "spiral". Find projectx.log and open it with your favorite text editor. Copy and paste it into a new post in your own thread.

I didn't understand any of that!
Please, make a post on this thread! I want to make this as easy to follow as possible.
