Lisa:
You have to go in to your pinterest settings and click OFF the search engine button.
If the button is on then your pins are hidden from search engines.

I was able to use Pinterest right away. I did not need anyone "under" me. I did however need a Facebook account to join AND had to be "invited' by someone. I do remember there was a post about another similar site where you did need to sign up 5 in order to use it.
In general:
I don't think it's against policy to "pin" Etsy items as there is a pin it button with every listing. I pin many of my own and others.
I have a few boards and really enjoy the ease of use. I like to follow fashion, pop culture, retro stuff and have picked up some amazing recipes. Not to mention cool places I'd like to visit!

P.S. If anyone needs an invite, I'd be happen to do so, just convo me.
Thanks!
