Just to be a little more specific, it's just some text displayed on a single page of a website that the site owners will be able to change via the admin interface (it's actually two pieces of text: the version as the user input it and the html formatted version).

That rules out web.config because I don't want to change that from code (has some nasty side-effects like resetting the application). I could use a flat file though. Such an ExtendedProperties table might be an idea, but the only thing it'd hold for the foreseeable future would be that piece of text.
