Constellation36: And why some players have more than 100-200 started games at a certain time? I mean if they can't keep up with so many games they should not play them and not play like snails.

The number of games a person has says little about his/her ability to play.
I used to have almost 900 games running at one time. Every day I brought my waiting games list down to 0. Many of the games I didn't play every day, though, because my opponents weren't fast enough. Others I played over a dozen moves a day, because my opponent moved as soon as I did.
If I waited for those games to finish before starting new ones, I'd still be waiting for those that aren't that fast to play...
Just to say that having 100-200 games, doesn't mean much per se...
