I recently found this tool and I think it's very useful. At work we use our own site hosted by ning.com byt PENZU could be very useful for any tutors running courses anywhere and who don't have access to a site on ning.com or don't want to create one and simple have the possibility to have their trainees' journals online.
Top tool for me because of my work context in teacher training. here's the link: http://penzu.com/
