[Phalanx]

Guys...might be getting a promotion type thing I threw in an expression of interest for at work...I met pretty much all thr criteria in the job specs...'cept for one thing I kind've bullshitted my way around;
How to use excel.
I never learned...to me, it's just something with alotta boxes you type shit into...but I KNOW there's more to it than that. It's (my) friday night here now, and I am heading in to get trialled/trained on tuesday morning...I need to brush up. Nothing crazy, I just need a basic understanding of operations...etc.
So, is there any info you could give me, or some sites you know of that I could use to brush up in a fairly quick way?

Thanks in advance. - B.
