I have several general, non-technical questions about MultiSite. I've seen tutorials and although they did a good job of explaining the set-up process, I'm even more confused about whether this is what I need and for some situations, what's the point?
I have three situations to ask about, two of which I really want to do.
1) A sub-directory blog that looks exactly like my primary blog
2) A sub-directory blog that looks completely different
3) A new blog on a different domain
#1. I wanted a "sub section" of my main blog only to write about one subject. Same exact look, same menu, same widgets, same everything except the posts from my main blog wouldn't show up in my sub-blog and posts from sub-blog wouldn't show up in my main blog. It sounds like multisite can help me maintain two separate blogs with one being a subdirectory of the other, but is there a way to make them automatically share the same theme, settings, plugins, menu items and more to make it appear to all be the same website? If not and I have to duplicate all the non-content elements myself, then wouldn't it be easier to just use cPanel to autoinstall a totally new and separate blog on that subdirectory in the first place?
#2. If I wanted a different look then most of my concerns from #1 wouldn't even matter. But again, if it's just a few minutes to auto install a new WordPress installation from cPanel anyway, then why should I bother setting up multisite? What's the advantage?
#3. I read that I can run a multisite blog on a different domain but I haven't found those instructions. How does that one work? Do users need to log in at my domain to blog on their blog on a different domain?
