Translation of bitteschön

I will built a function that will do all lowercase but meanwhile, I would be happy if it could be rewritten to lower case... Is it possible for you? They should all be lowercase, I did it inadvertently.
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?
It's very good for me to be a member at Vocabulix be because I meet many new people. I'm currently being trained to be travel consultant and I really need English and Spanish and maybe other languages.
