What is the Difference Between Blog and Microsite in Tribefii?

A Microsite is a website, while a Blog Campaign is a plugin that you can add to your microsite. You need to set up the Blog Campaign which you will then place on a Microsite Page.

You can create multiple Blog Campaigns for different purposes - from updates to news to even customer stories.  Blog Campaigns can be placed in multiple Microsite Pages on the same Microsite, or on different Microsites.
