Translation of silky in Spanish

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.
Take your time to answer me, do the vocabulary exercises and measure your progress! Your answers will be kept in the system itself. After that you can look at the statistics. That's pretty cool here.
I would also like to thank you for your interesting phone call on Friday 4 weeks ago. As you have proposed at that time, I will bring up a few ideas for possible cooperation in the future.
