WordPress MU

I apologise if this has been discussed previously but I have searched.

Is there a way of getting my adsense adverts to appear on all users blogs not just the main page, I am using subdirectories not sub domains.
At present I'm using adpaster plugin.

Add the code for all templates (smink).

Pretty much. Either that or write a plugin with a header hook.

Thanks I didnt realise the different templates for users.
I am learning I think. :)
