I'm in the process of designing a new website, and I have a question about whether to use multisite or a single website with different templates. I'm familiar with creating templates, so that's not a problem. It's just a matter of what would be the best for the website.
The website will be "divided" in 3 or 4 "levels". Like:
Level one: main stuff. Blog section (one category only, like annoucements, so no need for different categories or such), pages and links.
Level two: accessible from level one, will contain pages, maybe a blog section (which might have multiple categories).
Level three: accessible from level two, but password protected. Will definitely have a blog section with multiple categories.
On top of that, I'll have, after a while, a blog, separated from the rest of the "main" website, with it's own subdomain name.
The different "levels" websites won't have their own subdomain, they will each be on the main domain. However, the menus will be differents.
What would be the best approach to that? Templates will be a bit of work, but I think it's doable. I've never tested the multisites feature, but I'm not sure my project isn't "too small" for a multisite installation to make sense. The main work will be making the templates, but I would have to code new themes for the multisites anyway, so it would probably end up being the same. There will be a bunch of plugins that I would want to use on all "level" websites, and with a multisite install, I have the impression each would have their own plugins, so it would mean activating and settings them for each website.
Thanks for all advice!
