For historical reasons, Norman Wikipedia can be found at nrm:
For historical reasons, Norman Wikipedia (including Guernésiais and Jèrriais dialects), was created with language code nrm, even though that is properly the language code for Narom (a Malayo-Polynesian language spoken by the Narom people in Sarawak, Malaysia). It is hoped that we will be able to move Norman Wikipedia to nrf.wikipedia.org in the near future; see phab:T25216.
IMPORTANT INFORMATION For the potential Narom users:
Unfortunately, it is not currently technically possible to start creating Narom Wikipedia here, when anyone is attempting to create pages (visit Wp/nrm/(somepage) and attach "?action=edit" after URL), they got a freak message:
This wiki already exists. You can find this page on [/wiki/Main Page wiki/Main Page]. If the wiki was recently created, please wait a few hours or days until all content is imported.
WHY? This is because the Norman Wikipedia exists at this location and the database name nrmwiki is reserved for that wiki, then any attemps to create subpages that have prefix "Wp/nrm/" will trigger codes from WikimediaIncubator.class.php (Ctrl+F search "wminc-error-wiki-exists" to find trigger conditions). How about creating other Narom Wikimedia Projects? You can just find one of them below, those are no longer assigned to Norman. Waiting for how many years to unlock creating of "Wp/nrm/" pages? You can read discussions in this gerrit patch if you're interested in it.
If I must create Narom Wikipedia right now, then where to go? Don't worry, you can ask one of our Incubator users on Incubator:Community Portal, then we'll start an urgent discussion to decide a special, temporary language code for you to use.
