Translations:Help:Changing your wiki license/19/en

Basically, you change user messages to read something like "By submitting this, you agree to assign copyright to (whomever)." This isn't always nice to contributors because it means they can't copy their writing without permission. It may be more desirable in private group settings, where these things are already arranged financially. This may otherwise be on shaky legal ground, as it implies a contract in which one party signs away property in exchange for no consideration.
