Problem: Many new editors don't notice the new messages popup in the right hand corner, which leads to them not reading important feedback about their edits.
Proposed solution: Have a one-time popup that appears when the user gets the first user talk post so the user knows they received a new message. Also, have some sort of global opt-out available so that stewards etc. don't have to click through this over and over.
Who would benefit: Nouveaux édituers, administrateurs
