I can't believe all this time I've been moaning about getting the contents of my posts to appear on the page when you click a month in the archive, all I needed to do was change:

<uc1:EntryList id="Days" DescriptionOnly = "true" runat="server"></uc1:EntryList>  in archivemonth.ascx within the folder for the skin I'm using to:

<uc1:EntryList id="Days" DescriptionOnly = "false" runat="server"></uc1:EntryList>

While I'm at it, here's another tip:  If you're like me and you post long lines of code (and you're using the PIYO skin made by the illustrious Code Climber and friends) , why not make the default full screen:

Go into header.ascx and add the line in bold:

<script type="text/javascript">
setActiveStyleSheet("elastic");
writeSwitcher();
</script>

It doesn't appear to mess up any cookie settings.   Ideally anything and everything would be configurable via admin, but since the subtext team, not to mention myself,  have plenty of bigger fish to fry, you can just follow my tips in the meanwhile.
