Hongyun needs a document management system for her class since her classmates are lazy and don't want to meet up to do work. I thought about doing sharepoint portal services, but it costs about $40/month after the initial 30 day free trial...quite steep. I'll just section off part of my webspace (yet again) and use it for this:

SourceForge.net: Project Info - KnowledgeTree Document Management Server

Looks neat...
