2.3 has a small change in the Reviews System. On older osCommerce versions, the review system was very prone to abuse as all reviews would be instantly available on site. Though HTML was stripped out (therefore stopping spammers from posting links), your shop could easily be the victim of a competitor or a disgruntled customer posting negative comments.
New Feature
What has been added is a new “status” feature where you can switch off any reviews easily;
Simply click the red button to turn off, and the green button to turn on.
All new reviews are entered into the database with an “off” status. So, you, the shop owner can read the review and make sure that it is something that you want to display on your site!
Other changes
The number of reviews (with status of “on”) shows as part of the button text on the individual product page;
Other features
Shop Owner is also able to edit and delete any review. Would suggest that editing a review is not great as you don’t want to be accused of putting words into your customers mouth. If you don’t like a review, just delete it, would be my advice;
The edit feature is a good idea because a lot of people can’t speell.
That’s exactly the reason to leave it asis, how else will your customer who can’t spell find the (misspelled) product ?
