Do I have to HTML encode this myself?

hi,

you can't add HTML from a simple TextBox. remove the <p>s and it will work.

Of course you can add HTML from a text box. But you need to add ValidateRequest="false" to the page directives for Administration\SettingDetails.aspx. I don't think you need to validate the administrator's text.
