Ok I need help 
I have never used Sharepoint in my life.
I'm the network admin for a travel company of about 100 users.
My ex boss purchased Sharepoint Server 2007, now hes left and Im being left to set this up.
I haven't a clue where to start. I mean, Ive installed the actual software, setup the database for it etc.
But ...then what.
I know this sounds stupid but, I open up the web interface where the portal is, but it all seems very overwhelming.
Are there any good tutorials for Sharepoint noobies? I havent had much luck on google, only found simple installation instructions.
Any advice appreciated
