I am planning to buy this module for making one of my Joomla website as central administrator. I will be connecting it to more than 15 website. Can I choose to publish an article on any number of websites selectively, i.e. I may want to publish on 1, I may want to publish on 3, or I may want to publish on all 15. It could be any variation.

MightySites can either share ALL articles or not share them at all.
So there are 2 variants:
1. All sites use own articles as usual and each site controls own articles as usual.
2. All sites share articles, so unpublishing any article in any site will affect this article in all sites.
