WordPress MU

I am running the 1.5 RC1 version and I'm wondering about Gravatars. The new admin interface allows setting Avatars support on and off. Admin-->Discussion-->Avatars. I've looked into adding Gravatar support to theme and it seems pretty straight forward by adding some code to the comments.php file.

Then I wondered, do all of the themes I have need to be edited to support Gravatars? I thought there had to be a plugin for this, and I found one here http://www.gravatar.com/implement.php#section_2_2 , but you would still need to call the function of this plugin in your theme.

So, I'm back to my question. Do I need to edit all of my installed theme's files in order to offer Gravatar support? If that is the case, I am using "Farms spectagular theme pack" from the WPMUDEV download area and I would be happy to be able to contribute to the MU community by editing these themes for Gravatar support.

Can someone please confirm that an easier answer doesn't exist? If it doesn't, I'll get to work.

Haven't done a thing to themes. Plugin puts gravatars in comments/posts automagically.

Thanks dsader, why do I always want to do things the hard way? :)

Wow, I don't mean to sound dense, but I have installed this plugin into mu-plugins and I don't see any options in admin and they are not showing on comments.

What could I be doing wrong? Does this work on wpmu 1.5 RC1?

Dashboard-->Design-->Gravatars

http://wordpress.org/extend/plugins/wp-gravatar/ works, too and has many more options (my preference).

once again, thanks dsader. I looked everywhere BUT under Design.

I will check out wp-gravatar...
