#Wikipedia consists of an ISO-639 code followed by "wikipedia.org". Because of the configuration of the Wikipedia domain, "www" is not necessary in front of an URL.
The Wawa language of Cameroon has as its ISO-639 code "www" and, this poses a problem; when you type www.wikipedia.org, you go to the portal. A functional URL for Wawa would be www.www.wikipedia.org.
This is quite cumbersome and this has been recognised as one of those corner cases that pose a problem. As we have someone from SIL on the language committee, the request for a Wawa Wikipedia came to the attention of Melinda Lyon. She has now proposed to change the code for Wawa to "wwx".
