Hello,
There is a request for a multilingual Wikibooks at < http://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikibooks_Multilin...
. I would like some input from the community about how to process it,
and whether or not it is a good idea.
I personally think this matter should be decided with Wikibooks and Foundation community consensus, because it is not a language subdomain as the language subcommittee normally processes (it would be a language-agnostic wiki for coordination and translation), it would overlap with existing Wikibooks subdomains and the Incubator, and it would be a major change in how the Wikibooks project is organized.
There are five multilingual projects to date, only two of which are for projects divided by language: the multilingual Wikisource and Beta Wikiversity. The other multilingual projects are Meta-Wiki, Wikispecies, and Commons.
(This message, and any other by any language subcommittee member, is an entirely unofficial personal comment.)
