We haven't write document for the skinning yet .
If you want to create your owner skin , the main steps are:
1. Create A folder to : CuteChat/Skins/YourFolderName
2. Create style.css and layout_ie.js , you could refer the samples
3. Set it to the web.config : <skins defaultFolder="YourFolderName">
the function InitializeChatLayout(skinfolder) is to creating layout table , and add the elements into the table .
You could find the element name in ChatUI_IE.ascx , such as 'divtop' ,' divmessagescontainer',''divroomtitle','divbottom'... etc
