3. When an action is performed on the white board, a small square appears in
the chat window under the most recent message. For a series actions in a row,
you will see a line of squares appearing. This keeps you aware of activities on
the white board.
4. Actions performed on the white board are noted on the scroll bar located on
the top left corner (see figure below).
5. Important events (e.g. when a member signs in/off; when the state of the room
is changed etc.) are posted on the chat log as system messages (see figure
below). Note that you can turn on/off system messages by clicking on the
button.
