where did you ever get that idea?

Mbin is a fork of kbin that continues to be developed. It’s not being developed as quickly as when the original dev was developing kbin, but it’s definitely enough to keep things running, and I honestly don’t have much I can complain about - it’s been pretty smooth running for me.

Mbin is very much still in active development. Where did you hear it wasn’t?

Are you confusing Mbin with /kbin maybe?
