Spell checker?

[patdart]

I set a friend up using an ibook I bought off eBay for her...a 
clamshell.  I loaded her with 9.1 and she's not interested in anything 
technical and it is primarily an email machine.  I loaded both Netscape 
and IE on it, but she wanted it very simple so I have her using 
Netscape for both browsing and mail.  She tells me that she needs a 
spell check app for her email (and frankly, I agree) and says it's not 
on Netscape.  I'm 4 hours away from the machine, but I'm  wondering 
when I do go, what I can set her up with that will have a spell check 
or a separate program for her to use.  I'd move her to X, but I don't 
remember what ram that machine has, so I fear I can't do it as it is.  
If I could Mail would be great, but I'm assuming I can't...

Any ideas for me?

Thanks,

Pat
