Padlet is a site for instant collaboration. Group members post what they are thinking and everyone can see the results immediately! It's a virtual "parking lot" or "bulletin board."
You can create an account, or you can just click on the button that states "Build a Wall." Once you begin to build a wall, you can send the link to others over e-mail, Facebook, Twitter, etc. by clicking on the "Share/Export" button on the right hand side of the wall. It looks like a little rectangle with an arrow coming out of it. You can also get an embed code to add it to a website/ blog through the same button.
A note listed on the website help button: "If you create a wall without logging in or signing up, you may be unable to edit the wall after 24 hours. You may still be able to post on it, but you may be unable to change the title, privacy settings etc."
You can also add headings, different backgrounds, media files, etc.
