The goal was to be able to open urls that were posted in comments in a new window instead of the actual (tiny) comment window. A couple little html tweaks and we're finished:
In the Comment Listing Template, add the following between <HEAD> and </HEAD>:
Then, find the line that begins <form method="post" and add the following just after:
so it looks more like this:
<form method="post" target="_self" action="
Note: You're simply adding target="_self" to the form tag. You don't need to add/delete anything else from the form tag.
Presto-chango! Now all links will open in a new window!
