Check out the link above and it will also give you a brief intro to the Karma and Acceptance point structure. Best way is to keep posting reviews, try to add photos if possible. First post in the "Newbie Report" section, and then when you level up, post in the other sub-forums according to geography.
Try hard to get to 500 Karma points (Lustful Lord) status, as the "Restricted Access Report" section opens up to you, and you will get LOTS of valuable reports.
I now almost post exclusively at the Restricted Acess section.
WELCOME and keep posting reviews! That is what drives this entire forum.
