Translation of Gravitation

Can we do it one day earlier? 30.April? I probably can't on the 04.05, but I will know just next week. Maybe we can do a phone lesson first and than the writing exercises. I do not feel ready yet.
Let me continue to tell you about my adventures. So, as I have told you in my last writing I returned to the airport and scheduled a new date for my flight. This time I left myself five more days.
About multiple translations: We want students to memorize 'idioma' and 'lengua' as they are both very common. The best we could do is to place them in 2 different lessons, so that users learn them both.
