A couple of the groups I'm on have 'Highlights' on the Discussion tab instead of giving the option of sorting by 'New posts' etc. The problem is that one of the groups I'm on I need to be able to sort by new because I'm one of the moderators. The other moderators can still sort. They don't know what happened. I thought it was just something those in charge had set up until the group I'm moderator also changed so I can't sort anymore. I've done some searching but I can't work out how to change it back. Ideas?
