Better version, you can specify the team in this, as well as the color:

pawn Код:

forward SendTeamMessage(teamid, color, const message[]);

public SendTeamMessage(teamid, color, const message[])
{
    for(new i; i < MAX_PLAYERS; i++)
    {
        if(!IsPlayerConnected(i)) continue;
        if(GetPlayerTeam(i) != teamid) continue;

        SendClientMessage(i, color, message);
    }
    return 1;
}

Just use it like a normal SendClientMessage, but replace 'playerid', with the teamid the message has to be sent to.
