Both arwiki and dewiki now has [[ https://meta.wikimedia.org/wiki/WMDE_Technical_Wishes/ReferencePreviews | ReferencePreviews ]], and both nowiki and nnwiki has expressed interest in tryiing out this awesome solution.
I've started threads about this on both projects; [[ https://no.wikipedia.org/wiki/Wikipedia:Tinget#Utpr%C3%B8ving_av_%C2%ABreference_previews%C2%BB | w:no:Wikipedia:Tinget#Utprøving av «reference previews» ]] and [[ https://nn.wikipedia.org/wiki/Wikipedia:Samfunnshuset#Utpr%C3%B8ving_av_%C2%ABreference_previews%C2%BB | w:nn:Wikipedia:Samfunnshuset#Utprøving av «reference previews» ]]. At nowiki we use an opinion polling (not voting!) to figure out if we really want this, and so far it seems to be a pretty clear trend. At nnwiki such questions are easier to answer, and if Ranveig says yes, then it is a go! Still hold on until after 5. June 2019.
Localization is done for both language variants, and I've asked the communities to review the translations. Please tell me if there are anything left that we should do.
Hold on to after 5. June 2019, the polling goes for one week at nowiki.
Even if the two Norwegian projects should be treated equally, one of them might choose not to use the extension.
