I started with IMP, but could never get through all the configuration files, and eventually gave up. TWIG is fantastic, just what I've been looking for to do group collaboration, scheduling, email etc. all from a web browser. The install instructions were clear and it all worked for me immediately. This package has web based administration, lots of configuration and customization abilities, and there is more in this software than first meets the eye. Great Job! Keep up the great work guys.
