It would be nice if the LangCom member, who has taken care about
creation of the particular project, writes at least a article about
the language and culture (and possible previously created projects)
and send it to wikimedia-l and to Wikimedia PR to publish it on
blog.wikimedia.org.
It doesn't have to be, but it would be definitely nice.
If the member who has lead the project up to creation doesn't
want/like/whatever writing such an article, please let us know and
somebody else could take that task.
