...and I really had no idea that this was the case!
I have just checked the relevant Facebook page for Folk Clubs UK and it gives three options on the Create an event page.These are:-

    * Invite members of the host group Folk Clubs UK
    * Anyone can view and RSVP (public event)
    * Show the guest list on the Event Page

... and each of them has a tick by them as default and I failed to notice this! I think this means that when I put up eight events in quick succession yesterday each of the 680 members got eight emails from me telling them of events that most of them had no hope of attending! I blush at the thought. I will make sure that I uncheck the * Invite members of the host group Folk Clubs UK option in future when I put up an event and apologise here for this.
