I recently observed that some of my friends chatting with on Gtalk were invisible! So, I asked them how’s this possible. They told me that they were chatting from Gmail chat box. But, I was sure there might be a way to get the invisible status working in Gtalk. While searching for it, I came across the Google Talk Labs Edition.
So how does GTalk differ from GTalk labs Edition? Well, there are a lot of differences. The Google Talk Labs Edition features group chats, smilies, tabbed chat boxes. And, you can also appear invisible to others by simply switching your status to invisible. But, unfortunately certain important features like voice chat, file transfers are missing. In addition to this you can’t send links to others. But, nevertheless it’s worth a try.
