Sorry, I should have been more clear. This is not a link they are creating themselves or that I am creating.
"Subscribers" (wordpress role) have a WordPress profile and those who have websites can enter their website address into a form in their profile.
WordPress automatically takes their website address and uses it to create a live link out of their name when that person makes a comment on my blog posts.
At this point, those links do not open in a new window.
My question is where do I go in the code to make a change so that whenever someone leaves a comment, that live link that gets created by WordPress is opening in a new window.
Thanks for anything you can share!
