I'm sort of new to the whole server thing, having started a new job. They have asked me to create a web interface for the server that they could pull files off of it and arrange a calendar and such in a pretty GUI. I was researching Zimbra, which has an opensource version. The problem is that most of these collaboration suites focus on e-mail. We already have adequate e-mail usage, and I'm looking for something to simply provide users with news, calendars that everyone can schedule things in to, as well as a place to put documents and such that people could pull them off and download them if they wanted. Is there software like this or should I use something like Zimbra without using the mail functionality?
Furthermore, has anyone used Zimbra? I'm wondering if this will be a good choice for the workplace.
