Using Workspace Chat in MS Groove
Workspace Chat in Microsoft Office Groove 2007 enables people to communicate inside a workspace of which they are all members. When you use Workspace Chat, other online members of the workspace will be alerted and can join the chat with a click of the mouse.
Click the Expand Chat arrow at the bottom of the Workspace Members pane. Type your message, and then press ENTER or click the Send chat entry arrow.
If you have a Tablet PC and prefer to use ink, click the arrow icon in the Chat pane, and then click Switch to Ink Mode.
