How does 2 people sharing the same computer affect my user settings

Communiqué stores the user settings file in each users profile directory in a folder named "Communiqué." Since each user has a separate user settings file, each user settings are saved intact and restored each time Communiqué is run. There is an exception to this, however, if 2 users share the same login credentials for the same computer then they also share the same user settings file. If you share the same user settings, it may not be as you left it especially if another user makes changes. To avoid this problem, you should use your own login credentials so your user settings for Communiqué are as you left them.
