Quite an accomplishment - 4,000,000 chess players in one place! I wonder how many are paying members?
Congrats To CHESS.COM!!!! 4,000,000 Members!

It is a well run site with many facilities for all types of player. I would be at a loss without it as I live in a very isolated spot. Its no joke dealing with four million people and its done professionally on this site.
I'd like to thank the staff and contributing players for their efforts.

Chess.com is pawning [pwning being the real word... yeah there are no good chess piece jokes that I know of].

It must be about time to set up another counter on the home page, this one counting downward and reflecting how many people are left who are not yet members of chess.com.
Attracting 4 million people to sign up for something of their own accord is amazing. It shows how much of a demand there is for your service and how well you've gone about providing for the demand, with features people expected from the start as well as new innovations you keep adding.

I wrote a blog about this...

Best wishes to the best chess site on the Internet!!
Chess.com has to go a lot ahead to be no.1 . They are not even near.
How are we defining no. 1? Simply the number of members?
