This is a well written paper and the review has been reflected accordingly. The paper itself is in an appropriate way embedded in the context of distance learning with a special focus on the use of SecondLife. The survey is based on a good set of research questions and the procedure itself is elaborated in an adequate way. This papers adds on existing experiences and can be regarded as rather useful for other, who intend to experiment in a similar direction. As such the potential and limitations are well displayed. All in all this paper keeps the attention of the reader from the beginning till the end.

Minor remark concerning the keywords: "Massive Multi-User Online 3D Virtual Environments" is a bit longish and it may be considered to split this up.

Concerning the tutor: It seems that the job of tutor is referring to a UK-system and not every reader my be 100% familiar with this. It could be advantageous to work this out. 
I seems that in the described case exactly one tutor was responsible. Or was there a change in personnel during the studio (i.e. did the same person introduce the students and stayed afterwards by means of SecondLife in touch with them?!
