Mantis2Go is an out of the box installation of MantisBT (a free popular web-based bugtracking system) for Windows.
Do not use for production purposes!
Maybe the easiest way to try MantisBT on Windows:
1. Start Mantis2Go installer
2. Choose directory where you want to install Mantis2Go (USB stick if you want)
3. Click "Yes" to start Mantis2Go
Support Incident Tracker (or SiT!) is a web based application for tracking technical support calls/emails. Engineers work to Service Level Agreements and incidents are flagged if they stray outside of them.
Manage purchasing orders, inventory and generate custom reports. Features include active directory authentication with support for user, group, access levels per user/group. Still in alpha stage.
