There are some problem I found out while using the review club.
Hope could help with the next release version.
- I don't know how the reviewer's rating come from, and there are no feedback function that sellers can rate the reviewers.
- There are no place to found out which reviewers we have sent the promo code to.
- The sellers cannot send internal message to the reviewer.
PS.For my own experience, I got the reviews about 20% out of the promo code used by the reviewers(The product were ordered on 18Jun, and all received by the reviewers).
