Hi,
A majority at no.wikipedia wants to start using the 'extendedconfirmed' group, see voting at https://no.wikipedia.org/w/index.php?title=Wikipedia:Tinget&oldid=18482053#Forslag_1_om_begrensning_av_oversetterfunksjonaliteten
Please create this group, configured the same way as it is at en.wikipedia. If I'm not mistaken, it should have autopromotion after 30 days/500 edits, be implicitly granted to sysops, and be grantable/revokable by sysops.
