Reading this nice blog, I have learnt about an interesting code review plug-in for Eclipse called Jupiter. Having installed and kicked the tyres, I can give it the official BMC double thumbs up!

The only issue I have is that it is based on Eclipse and most of the developers where I currently work use IDEA. I am after a tool for performing electronic code reviews and not resorting to printing out the code on paper. The only other open source tool I have found for code reviews is Codestriker. Be interested in hearing about any others.
