Is it possible to have Easytimeline (https://www.mediawiki.org/wiki/Extension:EasyTimeline) enabled on corsarius.miraheze.org?
Used by WMF; exempt from review.
Needs to be installed.
IIRC EasyTimeline is insatlled by default on Miraheze. The Meta's CoCC timeline is handled by EasyTimeline.
Just tested it, it is installed. I assumed it wasn't installed because it wasn't on the Manage Extensions list
