Communicate Coughing -- If you try the Communicate Lite demo mentioned in TidBITS #199, and you leave it connected but idle in the background, it will make a slight coughing noise every five minutes to let you know you are still connected, much as AppleLink does. The reminder helps you to avoid running up a phone bill or running down a PowerBook battery. If you don't like the sound, you can turn it off, pick another one, or increase the time between reminders.

You can make text bigger in Excel by zooming to a larger percentage with the Zoom control in the toolbar, or by selecting the cells containing too-small text, choosing Format > Cells (Command-1), and then setting options in the Font pane. You can also increase the default font size for new sheets by modifying the Size field (next to the Standard Font field) in the General pane of Excel's preferences.
