How to prevent links from opening in new windows?

[plasticsurgery]

I've tried everything on my end with the HTML and I couldn't figure anything out. I contacted vB support and this is what they said:

"That is the normal behavior for the URL code. Changing this requires modifying the code. If you have some coding ability then you can post on http://www.vbulletin.org for help with this. Otherwise you might find a premade addon for this on http://www.vbulletin.org."

Well on that note, does anyone know what the mod on the code is to do this? Or even better yet, is there a way just to stop this from occurring on links within your domain? Because all my links on here are just links to other parts of my website, a different forum/thread, etc so it's pretty silly to open up in a new window.

Thanks!
