Recently I have been using the code review plugin (Jupiter) for Eclipse. Installation is more or less straight forward, instructions are pretty useful. A common practice in many of the projects that I have worked so far is to write in-line comments (on paper) and/or use to-do tags while reviewing. With Jupiter, it is lot convenient and the code review can be done with in the IDE itself using the Review table and Review editor.

I have only used Configuration and Individual review phase so far and would like to try the other phases soon -- team review phase and rework phase. I'd be interested in knowing any experiences using the team review phase.

Update: Jupiter is now hosted on google code, updated the hyperlink to point to that.
