That is great to hear. Thanks for the responses!

Thanks. I will definitely keep Acquia in mind if (when) I run up against any issues.

That's great to hear that you've had success with this. We aren't 100% decided on features yet, but what I do know we want for sure are the following:

Integration with LDAP
A support ticketing system
Wiki-like content pages (with wysiwyg editing)
Document Management
Video Blog
News Feed for important announcements

Thanks Mr. Jax. I actually looked at Open Atrium, but it seems like it's a little too specific in it's functionality out-of-the-box. I would have to pare down some of the modules, as well as add several. Also, it seems more cumbersome than a standard Drupal installation to customize / theme. Though the default Atrium skin is pretty chic, we are going to have to create a custom look-and-feel for our project, and it seems more transparent how to do this for standard Drupal. I'm going to install them both separately and give 'em a try, though.

The results would have been published faster, but having a greater sample size generally tends to give more meaningful results.

It WOULD be fewer people. Exactly half as many.
