Two ways.
First way is you need to be recommended by three geordies of good standing. You'll then spend 90 days in meditation considering the geordie faith and your place within it. Following that, you'll spend 3 months training with a master in the tibetan mountains where your only sustenance will be signed pictures of Kevin Keegan and boiled 96 home shirts. You then begin the trials. You'll be starved, beaten and forced to repeatedly watch replays of the mackems beating us 3-0. If your faith is still resolute after months of this then you'll be forced to sit in the East Stand for a whole season. Assuming you survive that, you'll be placed in a 4' x 4' cell for a period of six months where your only food will be cheesy chips, your only drink blue pop and your only gratification your own sister. This is followed by a period of meditation and recovery before you may finally present yourself to the council, confirm your true black and white heart and be accepted into the brotherhood.
The other way is you send me your wechat id, I add you as a friend and add you to the group.
Much like Allardyce, I'd recommend route one.
