From Meta, a Wikimedia project coordination wiki
"Multilingual Wikipedia" refers to the many language editions Wikipedia has. This page serves for the communication with and between these editions.
Contacting Wikipedias 
- All Wikipedia Pin Board: If you have an information important to all Wikipedias, like news about elections or translatewiki.net news, put it (also) on this page. You will reach Wikipedians with this and do not have to put the information on every single village pump page.
New and small Wikipedias 
- Manual for small and new Wikipedias: tips how to improve your Wikipedia and find support
- Basic Wikipedia and help pages every Wikipedia should have: short and simple pages to translate (still at User:Ziko, comments and ideas are welcome)
- Small Wiki Monitoring Team: looks after small Wikipedias (and other projects) for example to fight against vandalism
- Wikimedia Incubator: for starting a new Wikipedia
