oh.. wait.. ;-)
Now its inserting like 3 ADDITIONAL paragraph marks (or hard returns) -- whatever you want to call them.. The only way I could tell was by pasting the code into MS Word and seeing them when I enabled "show P marks".....
any ideas for this problem?

I don't see any extra newlines... Where are they appearing?

They're hidden ... MS Word sees them when i paste, and apparantly my news app sees them.. because it's really messing up the output.. ;-(

<textarea>@{join("",@text)}</textarea>
the proposed solution still returns an array; It needs to be taken out of array context.
Instead of print <<END ,
try:
print "<textarea>" . join ( "", @text ) ."</textarea>\n" ;
This is presuming, of course, that the "\n" is already on the end of each element of @text. if not, you might want to join them with "\n".
Also, be aware that some browsers may take it upon themselves to make each line ending a "\n\r" - especially if you cut and paste into the textarea. I make it a habit to:
$input =~ s/\r//g ;
On all submitted form values to clean it up.

Thanks to everyone for their help. It's working now. Here's the core file saving code for your reference. It removes unncessary line returns, etc.
if (defined $query->param('Submit')) {
open NEWNEWS, "> cgi/news.txt" || die "Cannot open file: $!";
$result = $query->param('content');
$result =~ s/\r//g;
print NEWNEWS $result;
close(NEWNEWS);
print '<p>Saved your changes.</p>';
$query->delete('Submit');
}

I tried reading the source .. and used that code-- it runs w/o errors, but unfortunately didn't fix..
I used:
print "<textarea>" . join ( "", @text ) ."</textarea>\n" ;
hmm.. this is really strange. any other ideas?>

I'm not sure what the problem is, but I'll add a couple of
ways to interpolate an array without spaces...
print "<textarea>", @text, "</textarea>\n";
# (unless you've redefined $,)
...or...
{
local $";
print "<textarea>@text</textarea>\n";
}
