A Collaborative translation community cannot get off the ground without someone who will look after it initially. This is not a small job. The community manager must be willing and able to invest significant amounts of time into making this happen.
Therefore, make sure you find and appoint a good community manager before you start. Ideally this is a person who should have prior experience in managing a Collaborative translation, or other similar peer-production communities. If you cannot find a person with this kind of experience, make sure you schedule some time for learning best practices of Collaborative translation and peer production (for example, by reading content on the Collaborative Translation Patterns repository).
