The member services section which used to be available in the old classifieds system, has now gotten an equivalent in the vendor program as the first tier. If you pay the subscription fee for Tier1, you will be able to post and ad in the member services program; nothing more. the full vendor program will be implemented as tier 2. So if you are an existing vendor or want full vendor benefits, wait for tier 2.
The cost is either 50$ per year, or 15$ per quarter.
