Stixy is another online noticeboard tool, a rather cool rival to WallWisher.

Stixy allows you to create tasks, appointments, files, photos, notes, and bookmarks on their Stixyboards, organized in whatever way makes sense to them. Then they can share Stixyboards with friends, family, and colleagues.

You can control who has access, and whether visitors can read or amend the board.

It’s well worth a look:
