Max:
The new RVPR website has a lot more functionality including things such as "Report this post" capability so errors in posts can be easily flagged.
Also, there is far more control over park attributes (is there a pool? shade? playground?) There can be more attributes listed for a park than is presently possible but they cannot be directly changed by users. Users can "suggest an edit for this park" which will create a flag that an admin can evaluate and make the change if it is appropriate. That will prevent people from, for example, saying that a park doesn't have a pool just because it was closed when they visited.
Also park owners have the ability to "claim this listing" so they can keep data current about their own parks.
