Sounds easy.....

Code:
on *:JOIN:#matrixx:{
  mode $chan +v $nick
  .notice $nick Hello $nick Welcome to the Matrixx Help Menu: Feel free to use the following commands: !register, !forum, !general, !welcome, !crazy, !rules, !faq
}

on *:TEXT:!menu:#matrixx:{
  .notice $nick Welcome to the Help Menu: Feel free to use the following commands: !register, !forum, !general, !welcome, !crazy, !rules, !faq
}


Just unload the other 2 scripts that you now have.
Create 1 new remote file, and paste the above code.

It will:
- voice everyone that join channel #matrixx
- notice everyone that joins with the help menu.
- notice the help menu when someone types !menu

Good luck.
