A little help...

So, is there anyone out there willing to beta a Halo story for me? Chief/Cortana friendship...about 1.5k or so words (I haven't finished it yet)...you don't *have* to know First Stike (though, it would give you a little bit of background)...just looking for someone to point out obvious grammar mistakes and point out when I use the same word over and over (which I have a tendency to do, LOL)
