I've been an ass. No changes in the code for days, because paid work had taken all my time. Sorry guys.
First thing to do now is to separate the engine of the blog and the blog itself: right now everything is in the root directory, and that sucks terribly. It'd be more convenient to have the b2 files tidied in a /b2 directory and then the normal template file for the blog in any directory. When that is done, there'll be a first beta release.
Anyway, weither it'll be done by then or not, my personal blog will be powered by b2, from next monday.
