I'm running 3.0-RC1; I'm trying to update some WPMU plugins that set sitewide options - meaning "networkwide" in WP 3.0 speak, I suppose. "Site" in WP 3.0 seems to mean "blog".
1. First, I'm wondering what the equivalent of WPMU add_site_option(), get_site_option(), etc is in WP 3.0?
2. Second, what's the WP3 equivalent of the WPMU wpmu-options.php, as in:
<form method="post" action="wpmu-options.php">
when you're making a form for Site/Network admins to set plugin options? Is it ms-options.php?
