For a C# version, can anyone point me in the direction of a way where a user could login as an admin and add content to the events section of the first page? Ideally, it would have an expiration date after which the entered text would disappear. This functionality would resemble a CMS but in a very limited, specific way, targeting on small section of a page.

If you want an example of this try downloading the Subsonic Starter Kit and take a look at how they implement the content sections on physical pages.  It will give you some ideas on how to implement it.  I don't believe that it has an expiry date but that could be implemented.

 William,

Thank you very much. That link will get me started in the right direction. Then I'll look into how to have to update expire after 24 hours or so.

I appreciate your help.
