There had been a short discussion
Room owner 1: I was more thinking along the lines of, would it help to remove/add the feed again?
Room owner 2: you can try for sure
which unfortunately resulted in "Today is the day I killed Captain Obvious. Great. Just, great."
After digging arround here on Meta I found this post Can you set a new feeds user to take charge of more than one feed? where the op asked
"Is there a way to specifically assign an existing Feeds user to a feed? "
but unfortunately the answer from Marc Gravell had been
"At the moment, I can apply that manually - there is no existing UI to do that. But I guess it wouldn't really allow anything too harmful if we added it..."
So we can't change the user of the new-question-feed back to Captain Obvious by ourself. Could someone please do this for us?
