You can easily email a link to your calendar which your friends can click on to be taken directly to your online calendar.

You should first make sure your friends have access to your calendar by sharing your calendar or granting access to non-members.

You can then go to your calendar and click on the small green 'Email This' button. It will prompt you for their email addresses and you can type in a custom email message. When they receive the email, they do not receive a copy of the calendar, they receive a link they can click on that will take them to view your online calendar. 

Alternatively you can copy & paste your calendar's URL. You can include it in an email or any other document or web page you like.

Click on 'customize' and copy the link code from one of the gray boxes:

• Copy the "Link:" code that starts with "http://www.keepandshare.com" for a standard hyperlink URL.
• Copy the "Embed" code to actually embed your calendar inside of another website.
