Open profile link in new tab

Hi,
Thanks so much for this gist: https://gist.github.com/imath/6595222

I am wanting to open the profile page in a new browser tab (as i have instructions on a welcome page that they need to keep open).

Could you let me know how to modify the gist to achieve this? I am very new to php!
Thanks
