This page has been labelled for deletion.
The given reason is: unused (not a correct language code). And only an old test made a by single user, not working as expected and left behind. If things need to be adapted specifically for Cameroon, it should be done in a "Tagging guidelines for Cameroon" page, named explcitly without using a country code prefix. It will then be translatable using "FR:" prefix for French, or no prefix at all for English..
This normally means the page title is a bad one, and the content has been moved somewhere better. If a page title is vaguely meaningful, the page should perhaps be a redirect, or hold a small summary for historical interest instead. If you disagree with its deletion, please explain why on its talk page.
The page should now be empty apart from this message (as per procedure). The page history shows what used to be on this page, and allows people to rescue an old revision. We may decide to do this, but otherwise a wiki 'sysop' user can delete this page more permanently at some point. In the meantime we should fix any pages linking to here.
