Padlet, formerly know as Wallwisher has added a new feature called Streams. Posts in a Stream are in chronological order. It gives the posts a bit of a more structured look. In order to get to the Stream function, click on the Setting "cog" in the lower right hand corner, choose Layout, then click Stream. To see additional changes that have been made to Padlet, take a visit!
