Instant Messenger   
by Ilya S. Lyubinskiy   

The software has basically the same functionality as ICQ, MSN or Yahoo instant messengers. You can manage contact and ignore lists (that are kept on server), see online status of your contacts and have one-to-one communications. Additional features: build-in multi-user live chat, custom smileys, skins support. Server-side script is written for PHP/MySQL. A version with the banner space is available for additional price. The windows application can be customized/redesigned according to your needs.
