This code, in the posted by line, is what creates the link to the full article:
CODE
at <a href="<$MTEntryPermalink$>"><$MTEntryDate format="%X"$></a>
You can move the
CODE
<a href="<$MTEntryPermalink$>">...</a>
and replace ... with what you want to show as the link to the main article, if you want to change it....
does that help?
