Please could you tell me if its ok to cross post to another group? If it is, is it up to the person who posted the original to give permission, or up to the admin here? I have cross posted the health warning about ponds/algae and then wondered - perhaps too late - if it was ok to so so. Apologies if I have done the wrong thing. It seemed such an imortant warning and so mnay people use lakes and ponds to cool their digs off in this weather that I wanted to warn others about it.
