I am thinking about doing a complete graphic do-over of this blog due to the home and item templates being pretty messed up after all my editing and experimenting with them over the last couple of years. While I was going over some of the macros that you can use I found a nice little page with most (if not all) of the dasBlog macros described including syntax, screenshots and which version they are available from. It takes a lot of the guessing out of using the built in functionality.
I also found a customisation category at dasblog.info where you can find information about how customisation of the templates and themes works: http://dasblog.info/CategoryView,category,Customization.aspx
I have also switched the rss feed over to feedburner so that I can get some proper rss statistics.
