I'm currently considering converting my college newspaper's WordPress install into a multisite installation in order to create an extra blog that I would like to take a lot of the functionality from our current site to. In essence, they need to work together, which is why I'm leaning towards a multisite install. However, I've noticed that you lose the ability to set up user's accounts for them when you migrate to a multisite install.
That said, I have two questions. Firstly, is there a way that I can restore the ability for site admins to manually set up user's accounts for them?
Secondly, because we're a newspaper, the accounts that we create aren't actually used by anyone to log in, and in that sense are nothing more than a security vulnerability. Is there a way that "phantom" or "loginless" users could be added to WordPress, or perhaps is there another way that users could be managed in this type of setup, reserving the actual accounts for people that need to log in?
