I've looked everywhere for some information about this, but there just doesn't seem to be anything anywhere, the lack of info for multisite is really frustrating me!
If I setup a MU network of up to 80 sites, can I:
a) change the theme that they all use in one selection, or does each site's theme need to be changed through its own admin panel?
b) say I want to install a plugin. If I install it through Network Admin, will it automatically become active on all my sites?
thanks in advance
