Hi,
The Incubator-specific extension has been updated. The most notable
new feature is that the welcome pages for non-existing info pages are
now live on Incubator. For example
<http://incubator.wikimedia.org/wiki/Wp/nl> refers you to the Dutch
Wikipedia and <http://incubator.wikimedia.org/wiki/Wn/xmf> tells you
that it doesn't exist yet.
Some more info in my previous post:
