There’s a new version of P2 (this WP theme) out today but it’s not compatible with the current version of wordpress self-hosted unless you download the beta, which I’m not planning on doing. I installed it without properly reading the notes and it ended up making the blog not work.
I then proceeded to go and look for the original P2 version online somewhere and eventually found it. Everything is now back to normal, but I hope to get the new P2 soon. It is available on wordpress.com blogs so I checked that out with my test blog, and I really like the improvements. It addresses pretty much all the things I would have asked for, like more customization, more posting options including using titles when posting from the front page, and more.
