Activating Plugins on all blogs

Hi Guys!

Need some expert guidance :wink:

Is it possible to activate plugins from the main blog for all of the blogs within my installation of WPMU?

Also, is it possible, after a blog has been installed, to assign a theme to all existing blogs from my main install? I am using the default theme plugin – which works beautifully – but I need to change the theme on all of the blogs I have installed.

The goal of course for both of these questions is to not have to visit each of my blogs to make the updates manually.

//fingers crossed

Thanks in advance! – Scott
