Translation of beglaubigen

Do you speak German? How many languages can you really speak? I know Russian, English, Italian and some Spanish. I want to learn more Spanish, let's try to do it together? I love this forum.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
My daughter and her husband have invited me today, it is always very nice to visit them. There were many friends there too, because it was my grandson's birthday. We were very happy and celebrating.
