I understand that WP3 integrated MU-WP inside the core, so now is "pretty easy" create a network of sites.
However, I have some questions about this, because at my work we want to create a network, but already we have some sites, and I don't know how this could affect our current infrastructure.
- I read that, for a network or sites, wordpress impose certain rules in the url generated. is this true? because if is, it could destroy ten years of google indexing in our site... :(
- Could we managed differents themes for every site in the network?
- And finally, in a networks of site, we could manage the register user in a separated way, or all the user of the net have the same access to the rest of the network?
Thanks in advance.
