Free PHP Groupware project Needed Help

[annysharing]

Dear PHP experts,

I'm in the process of setting up a small film production company and I'm
planning to install a web-based groupware package. I was wondering if any of
you clever people could recommend a good groupware package, please?

I'd like:

- the ability to swap files (scripts, schedules, budgets etc)
- basic project management
- calendar
- contacts
- to-do lists
- wiki
- a media gallery would be excellent (photos, audio, movies)
Any one give sugggestion?
Thank you!
