I've just released the RPM package for NetOffice Dwins. NetOffice Dwins it's a free web based time tracking, timesheet, and project management environment. It includes groupware module, manage web projects with team collaboration, users management, tasks and projects tracking, files approval tracking, project sites clients access, customer relationship management, person evaluation, timesheet.
The package is available at my own repo. It's made for working with the stock distro plus the most used public repos. Seems to work in FC4 and CentOS5 systems. Hopefully it could be rebuilded on your favorite RPM distro without hassle. It's configured for working with the lovely PostgreSQL database instead of the hyped MySQL.
I plan to use Netoffice strongly in the next weeks. I hope it can fit to manage better my consulting work. That means I plan to maintain the package up to date. Hope it'll be useful to you.
