MediaWiki:Ipboptions is a page that each of your wikis should have. As an admin, you should be able to edit it like you would any other page. The difference being that this page (and all other system message pages) interpret their content as a simple string; so you can't do fancy stuff such as apply CSS to change appearance or use MediaWiki markup.
