I get at least one password reset a day on Zack.wordpress.com. I know I signed up years ago when this service went active. As you can tell I never use the website but I am not just going to give it away. If you want to own Zack.wordpress.com then feel free to contact me. You can email me direct at firstname.lastname@example.org.
I set that email up because I will probably get a ton of spam from here. So if you do email then make a subject that is attention grabbing.
