I've been... relatively absent from Subeta for the past couple of years. I was looking through my achievements as an additional way to glean all I missed (man there's just too much) and I'm wondering what the Battle Item Sorter is? I helped with the other item sorting Subeta did once, so I'd be interested in helping again. Is that still a thing? (The achievement isn't retired...) Where do I go for it? What is it?

Battle Item Sorter

There was also a news post about it here.

Thank you very much, I really appreciate it.
