I released a new WordPress / WPMU theme pack yesterday with 100 themes, lots of them new and some old favorites (like Mandigo) reworked to allow for custom uploaded headers.
What’s really really cool about these themes though is that because they’re all set up to work on Edublogs, they require absolutely no code editing at all.
Every sidebar is widgetized, every big header can be replaced through the backend of WP and (hopefully almost) every bug has been squashed.
So with any luck it’ll be of a lot of use to regular WP folk as well as WPMU-ers.
Incidentally, did you know that ‘Farms’ theme packs have been downloaded over 20 thousand times!
