WordPress MU

I need to deploy adsense code in my blog ASAP. I'm looking to have it on the primary domain and all subdomains when a new blogger signs up for a wp site. The only problem I'm having is protecting the plugin from new users and still having it active on there site. Can I deploy a pluging put my code in when they sign up and then remove their access to it while still active.

I found this plugin but can't figure out how to write the code so the ads run below the hear and above & below the first post.

Thanks,
Ken

Like I said in the other thread - dump this plugin file in mu-plugins folder. Nobody can touch it then. It will be always on. It will not show up in the admin area. Users will not be able to remove it or disable it.

The code above already places the ad at the end of the post.

Hi Andrea,

I got that, I need to have it above the first post, below and below the header and not sure how to do that with this code?

Go look in the codex for filters for those areas.

Where do I go for that?

When you're reading the codex, focus on the add_filter function - that's what's placing the adsense code where it shows up today.

Something else I found helpful is http://codex.wordpress.org/Writing_a_Plugin, which explains how to use hooks to insert your "stuff" in various pre-specified places in the code.

Thanks I'll take a look.
