Hide outbound URL's

Hi guys,
I’m using the old 6.6.3 theme, with a lot of customisation so I can’t upgrade easily.

I’m happy with the theme, but there’s something on the new version that I’d like to use.

It’s the link to the customer’s website from their listing page:
– when using the new theme it’s cloaked as: /out/POSTID/url
– but on my current theme I simply have the [URL] shortcode and get a straight forward no-follow link.

The only code I can see that looks like it’s the solution (from the new theme) is:

/out/<?php echo $post->ID; ?>/url/” rel=”noindex” target=”_blank”><?php echo $CORE->_e(array(‘button’,’12’)); ?>

I’m guessing I’ll have to edit my URL shortcode, but my programming skills aren’t anything to write home about, so can anyone give me any guidance on how to do this, either inline or on a section of backend code?

Thanks
