Hi all.

I would like to know what kind of online service / software do you use to work on a project (web development) when you are a team of 3 or 4 devs.

I need something to let us do some brainstorming to find the idea of our future web app, then to prioritize what feature need to be develop first, by who, when, etc.

I found Taiga.io (an open source service and an alternative to Trello) recently, and it seems to be a good choice when we will be on development.. what do you think ? Do you have any dev tools to recommend ?
