because its better to come down to ONE language instead of ONE translator-prog.^^
think of it, the possibility to get a question answered when you write in a language that 99% of the people here understand (lee doesnt speak suaheli in origin

) is much more given than posting in your own language and hope that someone is interested in answering.
you want to get help? so you have to do something for it. same with fpsc: talk to the prog without knowing its language (scripting)? no way.
if people want to talk in their own language they do their own local community, see german fpsc-board for example.
