Use timers for the time that you want to set ^_^, for showing rules only to the newly registered users do as follows:
At the top

Код:

 new fresh = 0;

Then after they have already registered and have just logged in type :

Код:

fresh = 1;

then in OnPlayerSpawn
type

Код:

if(fresh == 0 )
{
 // your message to the NEW players
}
// out here is what you want to say to the players coming back again or the players who died and respawned.

EDIT: Did i help you?
