Oh you have to be a member for a certain amount of time and have so many posts to get access....the exact rules are in the FAQ under the suggestions, comments, etc. forum. At that point you'll get also gain access to TAO (Talk Amongst Ourselves -- a fun miscellaneous gossipy forum) and Spirituality and maybe WAHM? Anyway Trading Post is awesome b/c there are no fees to list your stuff unlike eBay, and the mamas trade/sell nice used (and new!) things MUCH cheaper than you can find on eBay. And it's a very trustful community so you feel a certain confidence. That's what the ratings on your personal profile are for, in case you've ever wondered. They are for Trading Post transactions. I prolly should be keeping this to myself as much as possible
but in the spirit of MDC I'll tell ya that you can find awesome deals on Maternity clothes there.
