I generally go around every few months and add the new Mortal Engines art into the group. Of course, if anyone submits something, then I'll add it, too.
I personally love the name STALKER SHRIKE. But then again im in UK so thats all i've ever heard. It makes him feel real and more alive than GRIKE i think. And the reason in the US u get books later is cuz of whhen the publishers are free to publish them, and when they can agree with the authors on a date
