The read-only Wikipedia Tenth Anniversary Wiki currently has the url address ten.wikipedia.org.
The language code ten is assigned to the Tama language, an extinct indigenous language of Colombia in South America.
It is possible to create content pages on Incubator with the prefix Wp/ten.
In principle, if Tama Wikipedia becomes eligible for approval, it would normally be assigned the address "ten.wikipedia.org". If that approval happens, LangCom will have to decide how to resolve the conflict. Given that the language is extinct, that seems very unlikely.
This is an open test wiki in the Wikimedia Incubator.
If you know this language, you are encouraged to contribute!
This test wiki has not yet been started. If you know this language, follow the instructions on Special:MyLanguage/Help:Manual. You can create a Main Page at "Wp/ten/Main_Page" with "Main_Page" translated into this language (for example "Wp/fr/Accueil" if it were a French test wiki).
