After much searching for blogging software and using various ones in the past I have now settled on WordPress (www.wordpress.org).
I have previously used MoveableType (www.sixpart.com). Although I think it’s a great blogging tool, I find that it was taking too much of my time to update and maintain. Perhaps when I have more time I’ll migrate my blog to this again. Then it’s just figuring out how to migrate from one type of blogging software to another !
