Bellad, please check out the link below - you should find the information on the TER review process to be quite helpful.  It also supplies guidelines on what is necessary to include a link in your posts.

Since you will be working for an agency, you are not allowed to post ads on the discussion boards - the agency must do it for you as part of their weekly allotment.  But you may participate in the discussion threads, and are encouraged to do so.

Regarding reviews, you may wish to ask your clients after a session if they would be willing to write a review on TER.

To gain access to the Providers Only discussion board, you must already have a TER profile with three or more reviews.  Once you have met that requirement, simply email [email protected] with your TER username and the phone number or email address on your TER reviews, and put "Provider only board access" in the subject line of the email.

Best of luck!
