Pinterest Anyone?

Ok, so I have to be the dumbest gal out there. Why on earth can't I figure out Pinterest? They now have an iPhone app! Yeah! but there is no tutorial. I get that you are supposed to use it instead of bookmarking everything which would be more than awesome because hubby is never sure they will all be there after each update. I simply can't loose them all!

But I can't figure out how to pin something. And I can't figure out why it won't allow some of the board names I try to use. I've got the repinning thing now, finally, but I have no idea how to pin something I see while surfing. If anyone can help me out, I'll be so grateful. I might even love you forever!

ETA: I finally figured it out, the iPhone version anyway. You download the app, then you have to follow the instructions for installing a Bookmarklet. Put it somewhere easy to find, not at the bottom of a long list for example. Maybe give it it's own folder?? After that, when you want to 'pin' something (that is add it to one of your boards aka folders in your Pinterest account) you click on the little bookmark icon. NOT the + sign you would usually use to create a bookmark. Find the "Pin It" bookmark and click it. Now a bunch of thumbnail sized pictures should appear. Choose the one that best represents what you want to save and click it. It will then come up with a little button "Pin It". Click it and you will go to Pinterest to choose a board to save it under and add a title. Thats it. Not as hard as it sounds. Hope this helps someone.
