Hi:
For the guest name , you can add this script code into the end of the CuteSoft_Client/CuteChat/Channel.aspx :
<script>
SetGuestName("Chatter<%=Guid.NewGuid().ToString().Substring(0,4)%>")
</script>
The SetGuestName limit some characters . So If you want to allow symbol, you can change to :
<script>
chatclient.guestname="Chatter_<%=Guid.NewGuid().ToString().Substring(0,4)%>"
</script>
