@trinsec Ah, that would have been a good idea ;-)
But this really is a horrific UI fail: when you write a review, there’s no indication that you'll have to come up with a nickname. And then you don’t know whether you can change it. So the only option is “Cancel.”
@trinsec I now realize that it wasn’t obvious :-)
@true_mxp Ok, this made a lot more sense with that explanation. :)
