VMOSS (Volunteer Management Open Source Software) is a standalone volunteer management system, providing volunteer and project registration, monitoring, and reporting functionality. It was originally developed as part of the Sahana (LAMP) System.
Couldn't get it to run. Instead of <?php they have many places where there is simply <? There were way too many of these to fix by hand and there's no way to run it on my server as-is. Installation instructions were just so-so. They rely too heavily on an automated install process that crashes when everything is not just so. It would be better to simply edit a config file by hand. Too bad, this looked like the most promising of the "volunteer" apps on sourceforge. The others were either broken completely or lacked much functionality.
