Some ideas

This is more of a review of the web site and as a member what I would like to see in the web site.

The site could certainly use recoloring, instead of the existing color. Use a dark background and a light color text, say blue background and white, or blue background and yellow text etc.

In the login window the tabs need not be there, actually the tabs are not necessary at all. It is just my personal opinion. The tabs need not be there t all. Instead have a frame, have a vertical navigation or horizontal or even better have a menu that would "Category " which contains the sub menu like "Science" , "Business" etc.
Instead of the upload tab make that also as a menu option and make it "Submit"
Once I login the login information need not be displayed, well if you insist you can displayed it at the top of the page
Well the whole idea of have to download and read the content well I am not comfortable with that. If i want to read it I would read it on-line. So instead re-organize the material page.
First name it in such a way that it conveys the meaning that people get the idea that they are going to read some thing. You need to have more categories not just "Science" or "Business", allow the user to create a tag or category fir his/her writing.
Layout could be like

Title:
Category/Tag:
Summary:(This should be just one-line summary)
Content:(This is where the user actually submits his content)
Now the rating part
Have more rating option say : presentation, idea,content flow, consistency of writing, you can add few more like readability, over all quality.
Suggestions (this column would suggest how to improve)

The when presenting the material the table is actually required. You can have this layout

Title Author, Rating(if there is no rating, don't display 0 (zero) leave it blank) , Instead of genre have the text as "Category/Tag". If you want to have a table have it without the borders.

Have a search option, you can use both combinational search and a simple search.
The main idea would be to have it like a on-line library, where any body who is registered can come read and contact the author, if you know what I mean.

Guess I did too much on the ideas thing. Let me stop it here

Nothing personal meant, just my ideas and some of the idea which I have implemented in some of the software that I worked on.

Any way there is a similar web site called http://www.fanstory.com/index.jsp, have a look at it.
