Curiousity with links in discussions in forums that are embedded in Wordpress
if I put this link in a comment it opens a new tab as expected.
if I click on the discussion topic in the discussions page the discussion topic stays embedded.
If I put the same link in a discussion (as the first item) - when you click on the discussion topic in the discussions page it opens a new tab for the discussion.
can anybody replicate this, if you have a wordpress site.
the code to insert in discussion
