You need to have at least 5-6 (I think that is the number) posts in forums other than the classifieds/marketplace. So go introduced your self, anwers several questions, comment on someone's post that sort of thing. Then you should be able to private message people and access you inbox at the top left hand of the screen by cicking private messages located under awards. Hope this helps. If not contact one of the mods like msjinkzd via posting on one of her threads.
