I'm on there: http://pinterest.com/hettielynn/
but haven't pinned a whole lot. I think it's a good idea to have things you find that you would like to save. I know when I bookmark a site I often forget about it or can't remember how it was saved. Pinterest is a virtual bulletin board with all those interesting and fun things you find all in one place with a picture to boot. Bunny, I checked some of yours the other day and could just about repin everything! You have found some yummy treats. I hope you don't feel like you're being stalked!
My daughters use pinterest when they are planning birthday parties. They create a board for the party and pin lots of ideas as they find things in their searches. It really works well for this. My niece plans home school ideas. I did run into a problem a couple of nights ago when I tried to pin something. It kept asking me for a login and password to pin something after I was already logged in. I guess it was just a glitch because it works now.
Kathy, I haven't figured it all out either. I think the things you pin randomly show up on the main board. People you don't know will repin something you've pinned.
