Is there any way to publish at the same time as moderation?

I'm wondering if there is a way to make it so that when a user create a node, that it is not published. It awaits moderation. I could set the content type so that the content type is "unpublished" by default.

Is there a way to provide a message to the end-user that they need to wait for the administrator approval before the node will appear on the site when they save the node?

When my administrator logs into the site and goes to admin/content/moderate - and clicks on "moderate" to have it automatically publish the node?

Thanks for your help. So far this solves most of the issues that my client wants. Keep up the good work.
