If you havn't received your first review here you don't have an ID# yet.  
You can search for reviews of yourself by entering information specific to you like provider name, phone number or email address into the review search engine. When you have reviews, you can request they be linked to your TER user name so we can easily find them whenever you post something.
 If a gent is asking for your ID# so he can write a review, he doesn't need it and can leave that field blank on the review submission form.
