I just have to plug two of my favorite products here. They are absolutely great at what they do and make my life a LOT easier.
Confluence: This is an enterprise-grade Wiki for storing, categorizing, and searching documentation as well as collaboration. It is EASY to deploy, manage, and upgrade. Take a test drive of it.
Jira: This is a workflow tool allowing you to enter tasks & issues, track progress, and time spent on those. Our development team uses it for issue tracking and other things, but it is absolutely GREAT just like Confluence.
