Basicly put a topic in the Help section, with useful hints and stuff like 'Press ` to open your console (its usually the button left of 1 and above tab. Below escape if you lack brains). Of course, if this doesnt work the console is a virus the black screen behind your blockland when it runs.
In the console, you can enter things to make your game do cool things. They can also help you to fix things.
Say if you jet when you dont press anything and stop jetting when you do, type "jet();" (no commas) into the console and this will be fixed. By typing "jet();" when your jets arent broken, can break them. Dont worry, you can fix this again, by typing "jet();" again.
The above was a very basic example, and generally people who don't know how to do this, don't venture into the forums much.
Post yours and we might get this moved to help by badspot.
Be helpful and nice.
TL;DR
Make a massive topic with useful tips.
