Something on Familypedia has changed. We seem unable to go directly to our main input form as we used to (from clicking on red links in infoboxes).
We now have Semantic Drilldown (Version 2.0.1) and Semantic MediaWiki (Version 2.4.1) and - listed in a separate table of Special:Version - Semantic Forms (Version 3.7).
I've not checked whether all of those have changed since the last time I looked it up, so it's a work in progress. I or someone else should check this wiki and update where appropriate.
