ReviewBoard is a very productive tool to review code and I have realized that apache has this tool. https://reviews.apache.org/groups
So far, I have learnt that each project has its corresponding group in review board. I would like to use this tool to submit patches and code change, and other developers can review them and discuss the changes and provide feedbacks at coding level. I don't know who administrate reviewboard to request a new group for Corinthia project. Juande
