ICQ 8 allows you to chat the way you want: select either a single window mode to view your active contacts or tabs mode.
ICQ can check your mail for you. Simply add your email account and start receiving notifications about new emails in your inbox.
You can connect ICQ to popular social networks like Facebook, Odnoklassniki and Vkontakte, and to messengers like Google Talk, Mail.Ru Agent and others. Once you connect your accounts to ICQ, all your contacts from the social network or messenger will appear in your ICQ contact list.
