Originally, I wanted to create a new tab next to "Comments" tab. Just as it is done (or similar) on tne WikiNews site - see "Opinions" tab. It had previously been asked about this in my another thread, but unfortunately did not get answers and any solutions.

I tried to do so as indicated, but the new tab is located (jQuery code puts it) in the
<div id="p-views" class="vectorTabs"> section ("Read"|"Edit"|"History" tabs) not in the
<div id="p-namespaces" class="vectorTabs"> section ("Article"|"Discussion" tabs).
Because it's so hard to make a new tab, the only solution is to change "Comments" tab to the "Journal" tab in my case.
