i just joined few minutes ago. and atm, i have 2 people who is not responding. i don't like to wait🙂, anyways, i made a move, but he has not. if i delete, does that mean i lost the game?

No ,2 complete moves have to be made.

ok, thanks

correspondance chess is a LOT slower than real-time chess: never expect anyone to make a move in a few minutes. One move a day is more common, longer for others.
If you want to play fast real-time style chess, try the uChess site: there's a link to it below.
Or do both: why not after all? 🙂
