Hello again,
I'd also like to point out that the extension provides a number of translation aids
(List:
https://www.mediawiki.org/wiki/Help:Extension:Translate/Translation_aids#...
)
such as:
*InOtherLanguages: views the same message in other translation
*DocumentationAid: adds the ability to write sort of comments about the message itself
*MachineTranslationAid: makes use of existing engines; Google Translation, for instance,
gives excellent results that mostly need only little modification
