how do i contact WP about business matters?

i’m not having a prob with WP functionally. i want to start a new website, but when i look up the url i find that it’s a WP demo site that’s not being used for anything but a single sample page. i’m hoping that if i ask WP nicely if they would be willing to relinquish it to someone for whom the name is perfect, they might be amenable.

however, i can’t find anywhere on the site where one can contact WP for administrative matters such as this. any suggestions?

thank you!
