sorry! registering sub domain

Hello, first off I'm sorry for sending this email to most likely the absolutely wrong place. However on php.net it's the only place I can see talk about someone administering php.net's dns records. I hope if this is not you, you can point me in the right direction or tell me to pfo. I belong to the Calgary PHP group and a while back we were thinking of moving some of our site around. Zak Greant said he might talk to someone there (not sure where there is) about getting calgary.php.net registered. Just wanting to know if this is possible. Thanks and again sorry for sending this inquiry here. Frank
