Word filter
The script filters out any unpleasant words that are sent or received to/from the user. it comes with a list of words so that it can be used immediatly without having to add your own. However, that is easy to do just by clicking in the menu and typing away, no editing of external files! You can also use the menu to check which words have already been banned.
It also includes the option to turn all the characters in the curse word to asterisks, or whether to leave the first letter.
