From the http://wordpress.org/about/domains/
For various reasons related to our WordPress trademark, we ask if you’re going to start a site about WordPress or related to it that you not use “WordPress” in the domain name. Try using “wp” instead, or another variation. We’re not lawyers, but very good ones tell us we have to do this to preserve our trademark. Also many users have told us they find it confusing.
So, my question is does this website have some agreement from WordPress.org?
If yes, what are the requirements to be allowed to use the name WordPress in the title/logo and URL?
