I have two questions in regards to 3.0 and the multi-user system:
1.) Can I combine multiple existing installations into a single MU installation? I currently have 4 separate installations I'd like to retain, if possible, upon upgrading to 3.0 and enabling MU.
2.) Is there flexibility in the directory structuring? I ask because I currently have my site set up with users having one of two options - they either get a wordpress blog only in the directory /name/, OR they get access to the directory wholesale to make a homepage, with a wordpress blog at /name/blog/. Is this possible to maintain while using MU in 3.0?
If not, am I basically relegated to using /name/ as the blog locations, and using link structure to build a /main/ section or something along those lines for the rest of their content?
