Frequent Contacts See When You Are Online, Can Chat Instantly
Another kind of access is also added in the background, however. The friend or colleague can automatically see when you are online in the Google Talk network — via Gmail, for example — and ready for chat.
If you can forego that convenience and would rather decide individually who can and who cannot see when you are and when you are not online, Gmail provides this level of control as well. When somebody, frequent contact or new acquaintance, invites you to chat, you will be asked for your explicit approval.
