I created a WordPress Network (aka Multi) site which will host blogs for local authors, for free. It is very important that each blog reflect the identity if its author. Yet for obvious reasons I cannot create a theme for each individual author (imagine, 100 authors, 100 blogs).
So, I said, I wish if there is a theme that works under WordPress network, which allows a specific customization which will be stored in the specific blog directory, not in the theme itself (it it is stored in the theme itself, the customization will appear in all other blogs which use the same theme). So, for instance, a widget in the theme which I may use for displaying the authors photo, which is blog-dependent rather than theme-dependent.
I wish you understand what I mean :)
( what is this called?)
I am grateful for any help you may offer, or if you point me to where I can find a solution
