Gchore is a simple tool that tracks your chores, and reminds you to do them on a daily basis. It is not a general todo list, it is better suited for repeating tasks, such as taking out the garbage on mondays. Gchore is highly configurable, and many of it's features can be accessed through the preferences popup. One such preference is the email option. You can configure gchore to automatically email someone when a task is completed, or send out an email at a scheduled time, detailing what has been accomplished since the last email was sent.
The easiest way to start using gchore is to simply run it, and start adding tasks. It will automatically create all it's databases in your home directory. There is no need to move these, but you can if you would like to. Once you have added a task, gchore will start issuing reminders to you via popup windows. Once you complete the task, click "completed", or if you don't feel like doing it today, click "procrastinate".
