[wp-hackers] Question on multisite blogs

[Helen Hou-Sandi]

Plugins don't have to be network activated; they can be activated for an
individual site in that site's Dashboard.

Themes are not activated in the network admin, but rather enabled *for use*
by the network or a site. You can enable a theme for a single site by
editing it in the network admin. Actually activating a theme is also done in
that site's Dashboard.
