I started drafting a new front page page to the wiki in a sand box at http://wiki.openmediavault.org/index.php?title=User:Dfarning .
As wiki front page can be surprisingly complicated as one tries to encapsulate an entire project in a single screen
At this point I have gone with a simple structure answering the following questions:
1. What is OpenMediaWiki?
a. How do I make OpenmediaWiki meet my particular needs?
b. What is happening in the project?
2. Where do I get more information?
As it takes shape we can start moving parts of it to the main page.
