Wiki Spaces.

A Wiki is a useful space where you can share work and have group discussion  with as many people as you want. There is an administrator which determines who joins your group and then it can be used for research and for group discussions on things such as assignments. 

Things such as videos, pod casts, interviews and lots more can be posted on this site and shared immediately with your chosen audience. It is a brilliant way yo keep up to date with work, business plans and even work outside education when in need of your workplace's weekly rota for example.
