So I was talking to one of my group members today about Wiki and how they have used it for a project before. She said she did not think it was safe because any one can go onto the work you have posted on your wiki space and delete/alter your work without permission! After discussing this issue with my tutor she said that she has heard the same thing but apparently there is a way to know who changed the information and there is a way you can retain your work that is lost. This made me feel a little better however I still think it would have been safer to create a group Yola website - or a site that involves passwords to change information!
