There is no help file .
The help messages are stored as resource string ,
you could add these two resource as you want :
MsgHelpNormal
MsgHelpModerator
When you click the help button , CuteChat would send "/help" to server , and download these messages.
If you want to popup a link , just need to change it to (sample code:) <a href="yourlink.html"><img src='help.gif'></a>
