Yeah, I’m in the UK, and was invited to Beta test for one particular feature, via an ‘interest’ email. Had fun doing so, reported my results, and was rewarded accordingly, and as promised, in this particular case. I don’t suppose this is always the case, but it was for this particular feature.
I saw the recent invite for new Beta testers, published on this web site, and tried to join the program from the UK, but it would not allow me to join. I wrote to them to advise, and they replied that if and when they need to expand their Beta test program across Europe, the website will be amended to accept European addresses, and they will notify us via this forum.
Who knows if that will happen, but the mail they sent me implied that at some point it would.
