Translation of bolita

What do we do about the numbers? I skipped them because I wasn't sure. Because it is possible that somebody wants to know how to say 15 in Spanish. He should write out the word as 'fifteen', not as digits.
Spanish is very important and widespread. I want to improve my skills with the help of Vocabulix and its users. I'll be there looking for people and I hope that my new efforts will be helpful.
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.
