Whatever you do in EQUI_ChatWindow.xml. It will affect all chat windows..
You can probably get rid of both but I wouldn't remove the chatedit box.. You won't be able to see what you're typing
To remove the titlebar find this:
<Screen item = "ChatWindow">
<RelativePosition>false</RelativePosition>
<Location>
<X>95</X>
<Y>280</Y>
</Location>
<Size>
<CX>421</CX>
<CY>200</CY>
</Size>
<Style_VScroll>false</Style_VScroll>
<Style_HScroll>false</Style_HScroll>
<Style_Transparent>false</Style_Transparent>
<DrawTemplate>WDT_Def2</DrawTemplate>
<Style_Titlebar>true</Style_Titlebar> <----------change to false
to get rid of the chat input you might/should (never tested) be able to change this:
<Pieces>CW_ChatInput</Pieces>
to:
<!--<Pieces>CW_ChatInput</Pieces>-->
Edit2: On second thought! Removing the piece might cause a warning message, error, or even a crash from game. Thats why I don't know if that way will work or not..
The better way of doing it would be: Mess with the <Anchors> for CW_ChatInput and CW_ChatOutput.. doing it this way shouldn't cause any warnings, errors or crashes
edit: reworded alittle
