Does anyone know if all of the changes to the rules are posted in one place anywhere?
I was very surprised by the post below about updated reviews.

but the changes to Rule 8 are in the information that is presented when you attempt to submit a review. No sure if many other than relatively new reviewers read it every time...

Rule 9 is also showing that if you review a provider you've already reviewed the old review stays. I assume that holds for reviewing her a third, fourth, or....time if someone really wants to.

Just two big ones. Rule 8 and rule 9 and those are written in the Review Submission Guidelines. (Link below)  
There are more changes coming but they are still in beta testing mode.

Good to know. Maybe when a new change is made they could use italics or a different font color, so we know something is new or different.
