       // add your login/register variables and levels etc here I guess...
       // for example: 
       if(PlayerInfo[playerid][LoggedIn] != 1) // if they are not logged in
       {
              Kick(playerid);
              SendCllientMessage(playerid,color,"You Have Been Automatically Kicked. Reason:  Failed To Log-In On Time."); 
              KillTimer(kicktimer);
              // whatever messages u want
              // add whatever else
       }
}

Untested.
