Special:Contributions/newbies is used to watch contributions from newcomers. It goes to Special:Contributions?contribs=newbie. This is the equivalent of Special:RecentChanges?userExpLevel=newcomer
- For users who have RC filters, Special:Contributions/newbies should go to Special:RecentChanges?userExpLevel=newcomer to give more filtering options to users. It increases consistency, because filtering changes done by a group of people is clearly under RecentChanges scope instead of Contributions, which lists all edits done by one user.
- For users who have opted-out RC filters, Special:Contributions/newbies should go to Special:Contributions?contribs=newbie as usual.
