Happy New Year!

And off course, may you get to explore ,  I almost forgot : and many languages!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

-I like adding "all" when I want to speficy that I am addressing a large number of people or an uncertain number of people. I also like to use the phrase "may..." when wishing something for the holidays. Finally, the phrase "my best wishes.." sounds a bit to me like a false friend from the French sentence "mellieures voeux", I think it's correct in English but it doesn't sound natural.

Happy New Year

I wish you a Happy New Year !
My best wishes for good health, happiness and prosperity for the coming year
I almost forgot : and many languages !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Very good! Always capitalize all of Happy New Year (or Merry Christmas, or Happy Easter). Also, do not put a space between a word and "!" or "?". This is correct:

"Happy New Year!"

This is wrong:

" Happy New Year ! ".

I make the opposite mistake in French all the time! :-)
