Well, i seen some people in other snippets putting:
on *:JOIN:#: { mode $chan +v $nick } Etc. so here is some other ways of doing it:

Here is how to auto give somone modes:

If your not the owner of the channel:

on *:JOIN:#: { mode $chan +[mode] $nick }

Replace [mode] With:

V - Voice
H - Halfop
O - Op
A - Protect
Q - Owner

and replace # with the channel name or you will be setting modes in every channel your in, lol.

If your the owner of the chan:

/cs [cmd] # ADD [nick]

Replace [cmd] with:

VOP - Auto voice
HOP - Auto Halfop
AOP - Auto Op
SOP - Auto Protect
and there aint 1 for owner :) u got to link nickname's for that.

Replace [nick] with the person you want to add.

Thats pretty much the simplest form of auto modes.

If you want only your mates to get auto modes.. use:

on *:JOIN:#: { if ($nick isin %my.friends) { mode $chan +[mode] $nick } }

to add friends, use: /set %my.friends %my.friends [new friend]

to remove 1, u can use: 

//set %my.friends $remove(%my.friends,[friend to remove])

I will make a much better script of all these when i get time but there jst some basic scripts.
