I reckon we shouldn't get too hung up on regions and timescales here....we just need a few people close enough to each other to make it actually happen (wherever that might be). It would be good if it could happen sooner rather than later, 12-18 months away seems FAR too far away George!
I think people need to say:
a) if they are interested and, if so
b) where they are situated and how far they would be willing to travel (Josh's would take some serious beating!

), and
c) if they are willing to be the first host
All we need is just a few people serious enough to make it happen!
