Does anyone know where chess.com is based?

yep

Not one single person here know's. Wow!

http://www.chess.com/article/view/about-chesscom
Here is a great article about chess.com and the support team...
It is older and might need updating but interesting 

The Great Beyondo knows.  But he's not telling.

So how come Chess.com doesn't have a Wikipedia article when Yahoo! chess does?

    In the back of my home there is an out-house.....

OMG 

I have been here for more than 3 years and never ever read the legal#termsofservice !! 

Did I miss anything ?

You did read the bit about bears, didn't you?

In a nutshell: NO BEARS.

Chess.com is a collective hallucination,except for Eric who pays the bills.

Fortunately I could persuade them to delete that clause and replace it by:

I am no computer internet guy, pretty much useless and even I know.....lol

does it matter?

I need to right a business letter to a website, and i chose chess.com, does anyone know who i should send it too? 

If you need it to be physical, there is an address at the bottom of the Terms & Privacy page: https://www.chess.com/legal

Chess.com now does have a wikipedia

Chess.com, LLC
PO Box 60400
Palo Alto, CA 94306

I guess he'd probably misspell the address anyway ...

Those would be the fake servers.

Its located in the middle of nowhere.
