Dial-in numbers and passcodes for company meetings are just one example of what is now available on Google thanks to the Search Google Calendar feature, added to Google"s Web-based calendar service last November. Launched last year as part of Google"s effort to develop a series of Web-based productivity applications, Google Calendar gives users the choice of keeping calendar entries private or publishing them for the world to see, but some Google Calendar users appear to be sharing their calendar information without realizing it. Quite a few corporate calendars can be found on Google Calendar yielding such tidbits as the date and time of vendor meetings and names of projects in the works.
