It does, if you have the money to fund its development…
But I’m not really convinced the old system worked, as I did multiple transactions on the old boards and couldn’t even figure out how to leave feedback, nor did anyone ever prompt me to. For example @Glenacius_K sold me his Japan Tech Ribira through here about 2 years ago.
Yeah, it would be completely custom. The old feedback is preserved as agreed upon:

As @jhb8426 noted, best to do a search in Traders Feedback and see what others are saying about the user.
One thing we’re looking at is having the trade feedback topic for that user linked directly from their user card and/or profile – then you have one click access to leave feedback or read feedback, etc. To me this is the simplest thing that works.
