I upgraded to WordPress 2.1.  I also updated the k2 theme to the newest available which says it is supposed to work with the new WP2.1.

How is it so far?  Good I guess.  I don’t know the ins and outs nor do I really care but it’s good enough for me.  I enjoy using the WYSIWYG editor and they also implemented something really cool where you can switch between code and the WYSIWYG editor.  Toodles.
