Looking for case studies for documentation and affinity group meeting

If you've implemented CiviCRM, please consider adding a case study to http://wiki.civicrm.org/confluence/display/CRMDOC/Case+Studies or the forums at http://forum.civicrm.org/index.php/board,4.0.html. It would be great if you could include detailed descriptions of the implementation (custom fields used, profiles, special menus created for tasks) as well as obstacles, work-arounds, "results". Also, if you will be attending the NTEN conference, I hope you'll come to the CiviCRM Affinity Group meeting and speak up about how you are using CiviCRM. If you can do that, please let me know, hallman at email dot unc dot edu. I'd like to have an idea of how many case studies we'll have so we can allocate sufficient time.
