You can offer banner advertisements on the chat room. Chat rooms attract large numbers of users with similar demographic profiles, which creates a good opportunity for targeted marketing efforts that advertisers are willing to pay a premium for.
You can find the TopAds.ascx from ~/CuteSoft_Client/CuteChat/Advertising/ directory.
The TopAds User Control is responsible for displaying the top banner at the top of each chat room.
It contains a 468x80 image by default. You can insert the text/image/flash to display the needed ads HTML.
