I have registered and started to try Trello, from https://trello.com today, and it looks very nice. I can use it for my own lists, however I will perhaps not be able to share with people for projects, because Trello is available in English only.
Also, I am a long time user of FOSS software (and a contributor too, I love contributing to FOSS).
This is why I am wondering: is there an equivalent to Trello in open source somewhere? I have started to search the web, and didn't find any so far. Does someone here know about one?
Eventually, would you know about one already provided with several languages even if not FOSS?
