My question is regarding directories, themes and plugins, their placment and hierarchy.
For example, if I create network, with two sites. And I enable, 1 theme and 1 plugin for both of them. Then I want to change this theme style or maybe even code in it, does it change for both of them or only for one?
To be more concerete, When I enable my theme for another site, does it copy this theme for him, in his own direcotry or it uses theme directory form main, my network directory?
