Ping service list in WP 3.0

I'm using Wordpress 3.0 with network i.e. multiple blogs in same install.

Earlier when I've used Wordpress I've had the opportunity to enter a list of ping services that are pinged after publishing a new post. In Wordpress 3.0 with networking enabled I don't find this functionality anywhere.

How could I change this? And is it somehow possible to make the list a default so all new blogs use it.

Any help is appreciated!
