I got the same email (as did others as mentioned in threads that I can't find quickly on here now!).
I was just wondering whether or not anyone has actually received their refund yet? I seem to recall seeing somewhere that refunds would be made after 18th July, but so far I haven't had mine.
I have to say that the website is rather lacking in any information about the cancelled event - it appears that the organisers think their diappointed entrants are best served by a pretence that the event was never conceived of in the first place!!
