Our demo website now includes this blog. All the code is in a single PHP file (blog.php - what else?) and a supporting CSS file. At this point the module only supports one language.
All the project files are available by SVN from the SourceForge project page at https://sourceforge.net/projects/targetcms/. The files in the repository are at times a little more up to date than the download pack on SourceForge and here on this site.
