Why?

I was providing clients with wpmu/wpms sites and I needed a way to make only certain themes available to certain site admins.

“This is already doable when you edit a blog in the admin.”

Technically it’s not. Remember, a site is different than a blog. 
A site contains blogs.
A site can be at Domain1.com while you have another site at Domain2.com, both with different sub-blogs underneath of them.

Instructions

I’ll hopefully have this up on the WordPress Plugin Database soon, but until then you can save the below txt document as a php file and upload to your plugins folder, activate and you’re good to go.

To add a theme that is site specific, simply make a folder called ms-themes in your wp-content directory.
In the ms-themes directory you create another folder with the same id as the site you want to add the theme to.

Example for Site with id of 7:
http://www.yourdomain.com/wp-content/ms-themes/7/

Any themes placed in the /7/ directory will be available for site_id 7.

Future Plans

• Done:  I plan to automagically create the ms-themes directory.
• Have option to automatically create site directories.
• Output display for easy recognition of what a site’s ID is.
