Wishes on the wall

Wallwisher allows us to post thoughts in the form of stickys on "walls". This is useful as if we are doing projects, we can share our thoughts via this website. The only bad thing about this is the character limit. We can post notes consisting of not more than 160 characters, and thus we are limited to short notes.We can use this in CCAs to tell other members of activities we could do for the CCA.
