Hi, guys. I built a forum called V2MM for Chinese freelancers, and I built a theme with the same name.

nodebb-theme-v2mm on github.

Its still under development, but there are a few unique features:

Show topics of subcategories in parent categories. Support special topics, such as external link topics. Special category template.
