It is few days now I am using new WP 2.2 and I feel like I like it :) Though I didn\’t yet managed to find a solution to my SpamKarma 2 problem, it still like it. For fighting spam bots, I have installed Bad Behavior plugin to cut off some crap, but I still have to go through the comments moderation process on a daily basis.
On the other hand, I start using widgets now and I like them a lot. I think in some time there will be a lot of widgets available from WP related sites (as currently there are a log of plugins).
I have also changed the theme since I am not in the mood of adjusting my old one, nor I am going to design something new. If anyone wants to try and make me a theme (with widget support) – I will be more than happy.
