Well, I am not sure what more we can elaborate on the Gabe's suggestions.
If you really want to use a functionality which is already implemented, then whatever you do, you will come back to the Generic Content. You can for example create a second provider for Generic Content, and restrict the people to access the content items from it. Then, you can build a user control which takes the content via our APIs. You can take a look at our APIs and the famous GetContent() method. You should have no more than 5-6 lines of code for this. What you win with this approach is that you will still be able to use the RadEditor for your formatting. Then, you can place this control anywhere in your application.
The other approach is to create a new table in the database, and query the database to take the content. You can also create an external file with the content you need (either plain text or html formatted), and read the data from it every time you need it.
