Yes, that's correct, the latest theme pack has 100 delicious, 100% WPMU compatible, WordPress themes all for you. They are full of widgets (every theme is widgetized) and customizable headers galore... but that's not all, not by a long shot. The pack also features

• Internationalization of every theme (assisted by the team from blogs.sch.gr)
• A new default theme based on the popular Cutline 3 column theme
• A massive amount of bug fixing and testing from use on Edublogs.org
• Full integration with WPMUDEV Premium avatars (in comments) and also Comment Form Text
• Improvement of themes like Mandigo, Oceanwide and Vertigo (all which now have uploadable custom headers!!!)

But here's the really big one... every theme now also allows you to serve ads, in exactly the same way wordpress.com does!

• Yep, we've uploaded to WPMUDEV Premium a customized version of Ozh's brilliant Who Sees Ads plugin (or you can customize it yourself from his release) and in each theme you'll see a bit of code that looks pretty much like this in a nicely positioned spot: ?php if (function_exists('wp_ozh_wsa')) { wp_ozh_wsa("336280nocolor"); } ?
• All you have to do is create the unit 336280nocolor in WSA, give it some rules (for example, only show for search engine visitors but never for regular visitors, logged in users or those visiting from a link or a direct bookmark) and hey presto... you've got a dynamic ad serving engine.
• You'll find about 50 different ad codes splashed around the themes with each one indicative of the size of ad that should be used and, for the more popular themes, specific to them. Here's hoping you enjoy muchly!
