Get reminder emails through Google Calender

I finally figured out how to do it.Go to your gmail account and click on the calender link on the top left.Create a new event, fill all the information required including when to repeat it. On the right side you can select whether you want to get email or pop ups, and how often should you get them. Also, to send reminders to a group of people, you can add their email addresses in the add guests tab.
