Hey JJR, I hope you don't mind, but since you created a hack that I really happened to need -- at the moment I needed it -- I made a couple of customizations that really suited my purposes.

This is one I think a lot of people might be interested in.

I've always liked being able to cut short a news article on the main page, say, to a paragraph or two. Then you can click on a "READ MORE" link or something to that effect, so you don't end up taking up so much space on your home page.

So, I've modified the aforeposted hack to add this functionality.

This extra little bit of code will read the post, separate out the paragraphs, and if the post runs longer than your preset maximum number of paragraphs, it adds a "MORE >>" link at the end of the text.

Around line 20-ish, you'll see a line like this:

PHP Code:

$gnpagetext=bbcodeparse($gnpagetext); 


After this line, insert the following code:

PHP Code:

$maxpars = 2;  // The maximum number of paragraphs you want to show
$gnpagetext=ereg_replace("(<br />|\n|\r)+", "\n", $gnpagetext);
$gnpagetext=ereg_replace("(\n)+", "\n", $gnpagetext);
$gnparagraphs=explode("\n", $gnpagetext);
for ($par = 0; (($par < $maxpars) and ($gnparagraphs[$par] <> "")); $par++) {
  $parcache[$par]=$gnparagraphs[$par];
}
$gnpagetext = implode("\n <br /><br /> \n", $parcache);
if ($gnparagraphs[$maxpars]) {
  $gnmorelink="<a href=\"showthread.php?s=$session[sessionhash]&threadid=$gnthreadid\">MORE »</a>";  
}
unset($parcache); 


$maxpars (in case you couldn't guess) is the maximum number of paragraphs you want to show. If you set it to 1, you'll only see one paragraph of the news, etc. etc. etc.

And you'll have to add $gnmorelink after $gnpagetext in the templates.

Please test it out! Enjoy!
