Hello,
I am a researcher in the GroupLens lab (http://grouplens.org) at the University of Minnesota. You might recognize previous work in Wikipedia like "Creating, Destroying, and Restoring Value in Wikipedia" (http://www-users.cs.umn.edu/~reid/papers/group282-priedhorsky.pdf).
As part of our continuing work within Wikipedia, my colleagues and I are conducting an academic (non-commercial) study in which we have developed a modification that is designed to help users work together more effectively by changing the interface for reverting other editors.
If you choose to participate in the study, you will be automatically assigned a Wikipedia gadget that will consist of a subset of the modifications we have developed. As part of the study, we will be logging your usage of the tool (ie. when you are reverting other editors). We will also be available for tech support and bug fixes. Most likely there will be a survey at the completion and the complete tool will be made available.
