Pre sales: Same users across subdomains

[independentCog]

The structure I would like to have for my joomla site is to have a wiki, forum and directory on sub domains and each have the same users and files as the main site. Is this possible with this extension?

It's possible, but for maintenance simplicity with having same files you should also have same Joomla core database tables, check last two case studies here:

In other words, it's single Joomla website which can be loaded via multiple domains and each domain displays slightly different versions while all actually have same data.
