Heres a few binds I use to help my sofing.

For those who don't know how to make a config file. Can be done with Microsoft Word or Notepad
Open your word processor and paste the script into it.
Then go to file > save.
Name the file, and make sure ".cfg" is placed at the end of the file. Ie. "Sniper.cfg"
