Testimonials

"Horde Groupware is probably not the first collaboration software that comes to mind when thinking about deploying a new system. Perhaps it should. Contrary to most of the popular collaboration software on the market such as Open-Xchange, Scalix and Zimbra, the guys behind Horde understand how to write efficient code and use appropriate tools."
