Translation of Photosynthese

My first stop was great. I went there by myself not knowing anyone. I hired a room for two nights and walked around the city. After I had moved to my second stop for another two days something strange happened.
As promised, I am sending you in the attachment a (very) little overview of some applications we created on Vocabulix. Please send me also some infos about your activities. When would be the best time to talk?
In order to see it you have to complete a lesson. I attached a screenshot. I did not place any rating there, so that it will not demotivate some of the users, especially the fresh beginners.
