In new network product "AVACS Live Chat" for mobile phones supporting JAVA applications, and PC computers (open chat) company "AVACS"(www.avacs.net) has realized popular functions and added a number of up-to-date abilities, directed to mobile phones. Among the main abilities of "AVACS Live Chat" are:

• exchange of personal messages outside the rooms;
• filling in the questionnaire and looking through the questionnaires of other users;
• using photos in questionnaires that became possible thanks to the widespread use of camera phones. For the users who does not have camera in their mobile phones the developers have foreseen the download of photos from the file on the mobile phone, through the WEB-site (http://www.avacs.net/livechat/) in the Internet or by E-mail;
• advanced search by questionnaire data;
• exchange of files, photos, music and melodies;
