Unfortunately Geoff, the more general chatty threads that are opened, the more it is open to misunderstanding s. There are loads of these threads being opened now, 2 on the weather, and about 10 others with chat about everything from soup to nuts, to coin a phrase.
I can see that this is obviously the way to go on the GW site, one only has to look at the amount of comments open chat gets compared to someone asking a gardener question.
Some attract no comments at all..
