Can someone who is NOT a group member contact the owner/moderator through those home page addresses?? When in YG I tried to contact a few group owners to ask questions about the group before I thought about joining but the messages always came back as undeliverable.? I would like that feature if at all possible.
Yes, it is possible, although it is a configuration option for each individual owner/moderator. If they have jointly decided that they don't want to be contacted, you cannot make them accept your inquiry.?
