If you guys are really serious about this then I suggest that you:

:arrow: Write Dom a request for a PGD sponsored event. List what you think should be the guidelines structure for all to follow. I don't mean he'll give you money, but he does have contacts, experience and the 'PGD brand' at his disposal. The rest is negotiable.

:arrow: Volunteer yourself to head/organize it. If possible enlist the help of another or others to help where required. Nothing comes out of thin air unfortunately.

:arrow: Advertise, advertise, advertize! As much as you are capable though. If not then you'll likely have only a very few interested people and not much of an 'event'. I found video and visible media to be quite a powerful method of reaching outside PGD it's self.
