Ability to link ideas
Another thing I've realized while using the multi-language feature is that this is not really what we need. In fact, that would be interesting is the idea to 'link' ideas together so that their vote count would be summed in the reports. This way, we could have a forum in french and one in english, but when an idea is similar to another, we could link them together rather than translating them (which is taking a significant amount of time!).
