It currently seems to be that Stage Storm is holding a monopoly over English scanlations of Glass Mask. Apparently, Stage Storm is a pretty good group, but my heavens are they secretive. I've actually found their website and Italian forum. It seems to be that they are one of those groups that only let you join if you have a certain number of posts (in Italian), which is seems pretty obnoxious to me but would have been fair enough if not for a tiny little 2-year-old statement hidden in a recess of the site that said the website is barring all members, even ones that have already been validated, from viewing the "restricted section"! Yet they still seem to be cranking out the
scanlations. Just updated today, in fact. And we wouldn't know this unless people have seen and read the releases. How do you get to them? Am I just hopelessly thick?

Complain to them and not us. We have no bearing on what the scanlation groups do
