I'd like to provide my clients a portal to view status, mockups, links to resources, etc... I don't need anything terribly complex, but I would rather grab something that's already out there than write it myself right now (plenty of client work to do!).
Any ideas? Suggestions?
Edit: Web development for fairly small busineeses. These are typically 3-6 month projects with 2-3 iterations per month. It's really just to demonstrate progress in an orderly fashion.
