Verb conjugation of "constatar" in Spanish

I've met the owner of Dessarmile, who has also already written you (after you came back from Thailand). However, he does not speak Spanish and therefore I do not think that they can be good friends.
Sometimes I visit Vocabulix to meet new people. It is true that one could do the same on Facebook, but the FB page is rather for friends, and you are less likely to contact strangers for this purpose.
I'd be very happy if we could write me. I have read your blog. Are you from the U.S.? Where exactly are you from, which state? I have visited Chicago last year because my grandma lives there.
