Doing so will allow you to place regular weekly ads, create your showcase, and get you access to the ladies-only sections of the site.
As far as reviews, gentlemen post a review of their session with you. They may do this here and/or a number of other sites dedicated to this business. There are both public and private sections of every review. Depending on several factors the private areas of the review is only available to gentlemen who have private access. Accountability in reviews is not generally an issue, when it does occur you always have the option to dispute the review or portions of the review by starting a new thread in the coed discussion area.
Your other question of members requesting appointments, I find no member here with that exact handle. Now that you have your own handle, I highly recommend that you request this member to PM you from his account here directly to you. When he does, you will easily be able to research his posts and reviews on Eccie. It sounds like you have the general idea on screening, excellent! I might also suggest you contacting P411, they are a national verification service that most everyone out here uses. That will open up a lot of doors for you and for the gentlemen that would like to see you.

You will find the gentlemen members here in WTX are a very honest bunch that treat the ladies well. They are very honest in their reviews and supportive to the ladies. In return, all we expect is great value, for the requested donation. I would also recommend that you reach out to some of the other ladies here, they can and should be a great support system for you. Ashley Ashton has always been a great one for helping and is local in El Paso.
Good luck and please let me or Johnnybax know about your verification credentials and if you have other questions.
