i definitely agree with users here telling feedback system need to be upgraded/improved. Should we open a thread or send a collective email to the administrators/moderators of modulargrid?
I encounter several user having bad experience and writing to them without gettin a useful response or a response at all.

here's my suggestions:

1) separate "buyer feedbacks" from "seller feedbacks"
2) add neutro feedback
3) add comment section to publicly discuss in case of negative or neutro

especially the first thing i guess would be easy to add
