I've done my bit
I'm not even with them actually, but some of my family are. It's actually their Most Rated suggestion on their website, so you would hope they actually start doing one at some point. Although I did tweet them about it last week, but the response was not exactly promising "We’ve no current plans, however we'll continue to monitor the market & review this again later."
Have you tweeted them Jakeway, it's always worth doing this as well as voting on their website.
