Here is a description of what it takes to write a review worthy of approval. It is taken from a post by St. Cristopher. At the top of the forum, click Forum Guidelines, then Premium Access Information for his entire post.
You may earn FREE Premium Access by contributing to the site with reviews. Reviews can be described as form-style templates that the user completes to summarize the details of his encounter for the readers. Each field, such as contact info, physical appearance, etc. is to be filled out thoroughly by the reviewer. The "Rest of the Story" field is intended to be used by the reviewer to complete a more detailed account of the important aspects of his appointment. This can range from the ease of scheduling, to the intimate details regarding the provider and your overall experience with her from start to finish. You may be as brief or as detailed as you feel comfortable with, but please understand for the review to bring value to the readers you should include enough details necessary to give them a good picture of what took place between you and the provider. The more details you include to help the reader make an informed decision will improve the value of your review and be appreciated by all.
Please note that it says each of the fields shall be filled out. That really does not mean "see website", or "between her and me", etc. Readers are looking for useable information. Also ROS description is absolutely necessary.
There have also been some really good posts written on this subject by other members. I am sure someone can give us a link.
