Since previous topic is closed, I'm opening a new one. I can conclude now that method described by Ze is not working. I translated or re-translated more than 300 strings (my estimation) and translation is still not deployed.
Even if this mechanism works, translators who regularly update translation are in same basket with other who translate several strings per month. For us who translate regularly and have almost whole translation finished, there should be more often deploy, even if there are lower number of strings.
