This isn't exactly code-related, but you guys know the best!
What's the best intranet/project management system?
I'm thinking about using Expression Engine to manage my own custom one.
Edit
PHP platform.
I need to set up projects, colaborate with partners, and let clients see the status of the project. Really just a shared basic to-do list, with a few extra features.
I like ActiveCollab a lot, but it's a little pricey...
