Who told you that? They were wrong. My newsreader only shows me messages
that I have not already read or choose to mark as unread. And that is
the default configuration.
And as has been pointed out about comp.lang.php, the results typically
are the same in comp.lang.javascript where not quoting or top-posting is
very seriously frowned up.

That is because I use Mail Controls to prevent unwanted email from
Spammers (not implying you though). As a result, the address I post with
doesn't recieve email from non-AOL members.

If I am understanding you, after the script gets loaded the page won't
tell you its been changed.
The way I have always gotten around the timing issue with that is to
load data in the .js file and then have the .js file call a function in
the main page.
sample.js:
//js code here
//....
someFunctionToDealWithTheData();
Then, the function will only get called *after* the data has loaded.

Take a look at this page:
<URL: http://members.aol.com/justhikk/ >
It is by no means a complete example and about half the sub-menus don't
work but you can look at the source code and the .js files and see how
it works. It has been so long since I worked on that page that it uses
language= in the script tag. Yikes! But the code does work.
If you have any questions about the code in that page. Why it's the way
it is or any other questions, post back and I will email you from an
email address you can reply to.
