I didn't find your story -- did you just submit it to the library? If so, there's a delay until Tiger converts the format and posts it.
To post a work here for review, you can either simply cut and paste it into the text box or, as I personally prefer, click on the "Go Advanced" button below the text box and click on the Staple-looking thing to attach your story as a word document. That's usually much easier to actually edit and repost, rather than just comment upon.
