Ask questions, post pictures, compliment others on their photos, just generally participate in the forum. The classifieds are intended to be a service provided for contributing board members, not a free marketplace for every hobby seller who comes along. I know that sounds a bit blunt but it's the truth and one of the reasons why the rules regarding the classifieds are in place, along with the scammer problems. Too many people have joined solely for scamming others so the board owners have tried to have people become established board users with a physical presence here aside from the classifieds.
