Issue tracking is an important part of the overall code review process. The "Resources" tab includes a couple of lists of tools such as Mantis, Redmine, FobBugz, Trac, and Jira. For simple applications you may simply choose to track issues in a spreadsheet. You can begin by downloading the Issue Tracking spreadsheet. This will give you a general idea of the items that you want to capture and then resolve throughout the process. Then check the "Resources" tab to learn about a few tools used in the community. Finally, discuss with peers to determine the best tool for your team.
