How to see the Check-In History of a particular user in TFS (TFS-2008)?
Here is an explanation on how to do this using TFS Sidekicks. A comment in the top voted answer asked for details, but I am unable to comment on posts so I added it as an answer.
Install TFS Sidekicks Connect to your TFS server Choose Tools | History Sidekick Select User under User name pull down. Select the branch or folder that you are interested in.
You will then see a list of changesets from that one user in the selected branch or folder.
