If the Stoop was a groundshare (i.e. you paid money for use of someone else's stadium), then so is the Hive. . Broncos share a home ground with Barnet and London Bees, that to me makes it a groundshare regardless of how the money is split.
The thing that I really don't understand is:
We know the whole admin has been replaced, we know that the new admin emailed thousands of people on a contact list it had been provided from the previous admin.
Why in hell were these people who were season ticket holders last year not on this list? What happened to the list of season ticketholders last year or in earlier years?
I still maintain that the new admin team don't have all of last years details so if they haven't contacted you yet I doubt they ever will. Therefore if you are waiting for the Broncos to contact you before you go again then you are in for a very long wait.
If I was in this position of wanting to see Broncos play and not being contacted then I would be ringing up and asking why I haven't been contacted. Obviously if you are looking for a reason not to go because of what has happened to date then not going because you haven't been contacted is very convenient for you.
