I have just upgraded this blog to WP 2.8. I cannot do the auto upgrading from my dashboard because of some problems with comment.php. So, I used ftp to send all the WP 2.8 files to my server.
I do not have time to explore yet but I know the widgets are easier to manage now because we can view several widgets at one go. Previously, it was a pain because we can only manage one widget at a time.
Now, I have to spend a lot of time to upgrade all my 20 WordPress blogs….Sigh….
