no automatically e-mail notification
Not in general, but for many issues the automatically e-mail notification for new answers is missing. Example: https://foodsharing.de/?page=bezirk&bid=881&sub=forum&tid=62458&pid=349825#tpost-349825
Also in several groups („Betriebe“) a new message doesn’t cause an e-mail, in some it still does. Example: https://foodsharing.de/?page=fsbetrieb&id=4108
