We send our regular messages on Whats App. We have many groups and will keep adding more over time. You only need to join one group, as the messages are the same across all groups.
Only admins are allowed to send messages, so you will not be bombarded with spam. If you try to join a group and it is full, just try another group.
DO NOT message admins, only email us via our contact form on this website. Your messages to Admins will more than likely be deleted.
