User:Agamitsudo has a Flow board on his talk page since July.
A few days ago, his account was renamed as Benoît Prieur. His Flow board didn't move, and he has now a standard talk page.
( Note from Danny: To fix the immediate problem, I moved the extra wikitext page to an archive. Then I moved the Flow board from Discussion utilisateur:Agamitsudo to Discussion utilisateur:Benoît Prieur. The general problem still needs to get fixed. )
