What happens when you try it?
There are no plans to put it back as it isn't something we're actively promoting anymore, but we left it available for everyone that is already using it.
Sorry - theQuin, because I'm a new user of this forum, it wouldn't allow me to post back straightaway and for some reason, when it did allow me, my post isn't appearing. It is working now (just needed refreshing) and you've just answered my other question - thanks.
