Scorched3D has the ability to filter out any "bad" words from player names or chat text.
To enable the word filtering you need to create a file that specifies the list of "bad" words. The words need to be in a file named filter-27270.xml (change the number to match the port that you are running the server on).
This file should be created in the normal Scorched3D configuration area:-
windows : c:\documents and settings\<username>\.scorched3d unix : ~/.scorched3d
This file is just a newline seperated list of words.
