[ 1 ] Press the "Start a discussion" on your left.
That's it!
Format
Discussion Title: (Script name | Game Name) or (Script usage (eg. server crash) | Game Name)
The field below it (where you post your scripts):

Note: To find the " ` " key, it should normally be to the left of the "1" key (If you're on keyboards with function keys).
If you're on keyboards with the function keys (f1, f2 etc), then hold shift and press the esc key (also next to the "1" key)
Note: If the script exceeds the character limit, you can upload it as a .txt or .lua file instead!
