Thanks guys for all the good infos. 👍😊 Gonna have a look into all that and see what I can come up with.

I know a little about session and cookie but how can I use that to know if a user is actually online and interact with him?

I have a general question. Just need to be put on the right direction. I made that little game I put on a server. Now I wish that 2 persons could play against each other online. So I made a signup/login and I can list all the users against which you would like to play. Now how could I know who is actually online and send him/her an alert when it is his/her turn to play? My first idea was to send emails every time it's a player turn to make a move; but there must be something more elegant to do in-game? I'm having a lot of fun coding that thing and any help would be great 🙂
