The chatfilter is really great. But unless I am completely missing something, some of the instructions in this thread are wrong.
Its correct that the file need to be named "chatfilter.ini" and saved in %userprofile%"\documents\guild wars"
You can use notepad.exe to edit and just save in UTF-8 format.
Syntax (the important part) below [ChatFilter] is simply: trigger = action, scope
Example:
For those of you uncomfortable creating a filter from scratch I have attached my current chatfilter.ini as a zip-file.
The last line (action = censor) is simply for testing whether a trigger works. Try changing "# testword" to: ecto: If your chatfilter.ini is in the right folder (working) the following:
"WTB 17 ecto" will display as "WTB 17 ----"
For convenience: Create a shortcut on your desktop to chatfilter.ini in your Documents\Guild Wars folder - Makes it a lot easier to change the file while ingame.
