I've been using WordPress since Nov. 2006 when I became disgusted with Google's Beta Blogger and its lack of support. Then, in June, 2007, I migrated from WordPress.com to WordPress.org when I established my own domain. Late last week I did the automatic upgrade from Version 2.2 to the current version, and it was like magic, everything worked fine. I had previously tried to manually upgrade and somehow blew it, so I restored the 2.2 version.
At any rate I'm only writing to say thank you to the folks at WordPress who provide, and continually improve, wonderful blogging software, and for free, no less.
