@0x010C That was not Krenairs message, that was mine :) As @Dereckson said, I would be easy to use the messages from enwp, in this case the right for your protection level would be 'editnewbieprotected" (You can define a custom name for the protection interface, but the protection log would use this name). But we can you use a new name too, so it is upon your community to decide, (I think you need only a short poll, but that's up to you to decide that, not my choice) and then we can change the config so that you can use the new level.
@Sebk I think your community should decide that, but thanks for proposals. In general I guess a three day poll is enough, but I don't know how the french community handles this.
(Changing the status to stalled till the community vote about the name has finished)
Ok, I already prepared the changes local, with the at the moment most popular name. (Of course I would change it, if another name has more consensus). So please write a comment here, if the poll is finished, then we can quick move forward.
So in general the patches are ready for deploy, but we need to create the sysmessages locally first, and clarify the thing with sysops/bots. I already posted both at the end of your poll.
