Zimbra as a portal.
I'm currently evaluating Zimbra to take over from our exchange setup. I have noticed there is a documents section can this be expanded so that Zimbra could be used as a company portal to provide;
1. Email / Calendar services
2. Document management to users (ie truck drivers can view all documents relating to the companies vehicle policy, and annual leave forms etc)
3. Helpdesk to log computer faults and get notes on fault
4. Lodge bug tracking tickets for our Business Software.
5. Forum / Wiki to discuss current projects for a Staff members area.
