Posting events to the Calendar is easy.
Click on the Calendar link near the top of the page. On this page you will find a "Post Event" link near the bottom of the page, click it. Enter a brief name for the event and select the date and room it should link to from the drop down list. Click the submit button.
Ok you are half way done....
Now you are taken to a new posting page inside the room you chose from the drop doen list. Create a detailed post about the event with all the juicy details. Use a similar title for this post as users will be able to see this post from the calendar but also as if it were a normal posting. Submit the post and you are done.
Now if you go back and view the calendar, you will see that your event links to your post.
