Hi,
The "Other projects sidebar" beta feature is already on by default in some projects, such as the Italian Wikipedia and the French Wikipedia. Search for otherProjectsLinksByDefault in http://noc.wikimedia.org/conf/highlight.php?file=InitialiseSettings.php
Is there any reason not to make it it on by default in all (or most) projects?
