Translation of Auflauf

I have considered the option to bring my friends from other social networks and invite them to join here. They can develop better language skills here. I'd love to pursue that goal, but I want to write in English.
The differences between Italian and Spanish are very small. But I see that you speak Spanish better than I speak English. It is still far from perfect, but that is already a start.
Of course I understand the reasons. I live in Thun, which is not far from Bern, our capital city. How come your Spanish is so good? Have you ever been to Switzerland. You are most welcome.
