I am also from the UK, i spoke to the dev over the phone a few days ago as i was looking into mining PayPro and was doing some research on it before i started.
Darren took the time to have a chat with me and was very friendly and helpful and answered all of my questions even though he must of been very busy.
The partnership with Paypoint is massive IMO, in the UK most newsagents corner shops supermarkets petrol stations have PayPoint machines for paying your bills etc
My local newsagents is 100m away and has PayPoint

and i live out in the countryside.
Here in the UK the quickest, easiest ways to get Bitcoin is via a service like instant-bitcoins, Bittylicious, quick-bitcoin or ZipZap. We cannot always deposit to exchanges from UK without huge fees.
I have invested BTC in PayPro and i am mining so i hope its all good.
I would also like to meet up for a coffee with the devs other PayPro miners users, are there any planned meet-ups?
