Njm, my hack will not generate any server load. The process is completed through JavaScript.
In other words, the client (browser) does the job, not the server.
About your request to open the link into a new tab/window:
Open vbulletin_global.js file (where you edited the code originally) and find:
Code:
window.location.href = link;
Replace it with:
Code:
window.open(link, '_blank');
You are done.
