Removing your Google web history couldn't be easier. here's are the steps how to delete
If you're chatting with someone, your recent conversation history is available by scrolling up within the chat window. To clear this recent history, click the actions menu at the top right of the chat window and select Clear Window. Note: clearing your chat window does not delete these messages from your conversation history.
To permanently delete part or all of your conversation:
1.Select See Full Conversation from the actions menu at the top right of your chat window.
2.Select Delete Messages... from the actions menu at the top of the conversation.
3.Check the individual messages you'd like to delete and click Delete Selected at the bottom of the page, or click Delete All to delete the whole conversation.

No, and Yahoo has a weird way of servicing its chat users. Yahoo Messenger holds its own chat history, while Yahoo Web Messenger (the Flash-based one) holds another chat history if you use it. Neither Yahoo Messenger nor Yahoo Web Messenger sync between each other to preserve chat history between sessions, and that Yahoo Mail has a chat feature that doesn't allow you the option of saving a chat history AT ALL makes one wonder about their competence.

There are many different Yahoo chat rooms. First of all a person would need an account for Yahoo Messenger. From there, he or she can join any available chat room.
