When the admin of a DNN portal gives you an RSVP Code for their site, you are intended to use that code to access features or sectoins of the site that a typical visitor is not allow to.  In order to take advantage of this opportunity, you will need to input the RSVP Code into the right place on the site. 

Here are the steps to accomplish this:

1. Login to the site.
2. Click on your name to access your account.
3. Click on the "Manage Services" link.
4. Enter the code in the "Enter RSVP Code" field.
5. Click the "Subscribe" link.
6. If your RSVP Code is valid, then you will be met with a message telling you to logoff and then log back on.  Do this.
7. When you log back on, your new features should be available to you.
