    consider using a privmsg to the person instead of a public tell. Keep a hash of $seenusers{"$nickname"} with the value being a epoch time. you know if the hash entry exists that you have said hi to this user before, and what time you have said hi, so you can calculate "hey I only want to say hi to users every 30 minutes and I have not said hi to this user for 4 hours and I am seeing him join the channel again ... must say hi"

      Right, It is suppose to be private.. but I'm stuck in the code part....and adding time to it is a bit more advanced. If you can send me the appropriate code that would be a help. Thanks!

        Well, what I would do is use a prebuilt module such as Net::IRC or better yet, POE::Component::IRC to handle the service setup and event model. After that I would place my code in the on_join event, and do something like the following psudo code: 
        
if ( exists $seenusers{"$nick"} ) {  # I have seen the user
          my $epochnow = time();
          #check to see if enough time has gone by to say hello again.
+..
          say_hello("$nick") if ($seenuser{"$nick"} - $epchnow >= $HiT
+imeDly );
          #  if that fails then we have said hello recently, don't do 
+again...
}  else {  
#First time $nick has been seen...
say_hello("$nick");
}


sub say_hello {
my ($nick) = @_;
privmsg($nick, "hey there bud, welcome to $channel...\n");
$seenusers=time();
}

        Now you will want to write it whithout using globals, and put more tests in there, and make a cleanup loop to clean the hash as the time to live is past so you dont get a huge hash after time. thats all up to you, that is just psudo code -- you will have to write your own app.
