Translation of bicentenary in Spanish

Will you be online in 1 hour? I saw your translations and had some comments: rainbow is it 'arco iris' or one word arcoisris? Usually all words appear lower case. Sometimes it is uppercase. It all depends.
We can communicate via Skype if it acceptable to you. It's easier. I can also write you via regular email and attach photos. My hobbies are hunting and mountain climbing. The later is pretty dangerous.
I like to read German literature. Thank you also for the site, it appears to be very interesting. I wish you a nice week and a lot of fun and passion on your honeymoon. See you soon my friend.
