Hi Wintonian, I see just 5 comments on the "chatroom popular with Listener crossword aficionados", one of them being a regular from this forum. Popular ?
The attitude expressed, "Sadly, there's not much we can do to prevent it..." speaks volumes about a certain kind of person who feels entitled to lay down the law. What isn't discussed is that the success of this forum is in large part due to the absolute refusal of the "popular" chatroom to help.
If they feel that, by getting help, solvers are in some way unfairly submitting entries, the chatroom brigade should really try to keep things in perspective. It's only a crossword puzzle. By attaching such unproportioned esteem and undue importance to consistently solving the Listener, they have contributed to their own downfall.
