You can log your chats, which is an especially useful feature when you're using Google Talk to chat with coworkers about projects or with family and friends about some activity that requires planning. A chat log is a record of your conversations.
By default, Google automatically logs your chats and stores those logs in your Gmail account, if you're using one. You can change your automatics log settings by clicking the Settings link at the top of the Google Talk window.
After clicking the Settings link, the Settings dialog box appears. Select Chat from the list on the left. On the Chat Settings screen, you can choose whether you want to log your chats or not.
If you choose to log your chats, you can access those logs anything. From you chat window, click the small downward arrow on the right side of your screen. As shown in the figure below, a pop-out menu appears. Select the View past chats option.
This options takes you to your Gmail account where your chats are logged. From this option, however, you'll only see the chats that have taken place with that person.
There is a way to have unlogged conversations with someone while still keeping regular logs of your chats. It's called "going off record." To go off the record -- and chat outside your log -- click the small downward arrow that you used to access chat logs. From the menu that appears, click Go off the record. A message appears in your chat window indicating you're off record. WHen you're ready to go back on the recrod, click the downward arrow again and select Stop chatting off the record.
