I have been looking for a good Microblog/twitter clone and came across
GelatoCMS.  I love the interface a straightforward approach to your CMS. 
We have a larger k-12 school district in Michigan and I would like to pilot
this software for possible use by teachers or students or both!  Roughly
19,000 potential users however, I would imagine a few hundred would try it out.

The problem is I cannot possibly add all these users 1 at a time.  Does
your software support LDAP or could it be integrated as an Activity with
Moodle LMS?

Just wondering.  I see a lot of potential and want to explore this in our
district.  Thanks, Chris
