Great workshop on Code Review by Jim Priest (The Crumb). Jim demoed a product called Review Board a product that integrates with Git or SVN and provides a mechanism and workflow for reviewing code in a team. Like coding standards it is probably more important that you do review code than exactly how you review it. Spending some time looking at what you and your team is doing with an eye toward improvement and consistency. Great Seminar Jim - I learned a lot.
Addendum - Jim also mentioned Smart Bear as a good resource for code reviews.
