Hello,
We currently only feature new writing and writing that has been nominated into the spotlight page because, generally, people are looking for new writing to read.
For those that wish to read older writing entries, they can either visit the author's portfolio (and scroll down in the portfolio) or visit our "Writing By Genre" page. You can go directly to the search page:
http://www.writers-network.com/search.cgi - You will notice that you are able to toggle/sort the results. You can choose to view older writing first.
The last option you have is to promote your own writing. We have created the "sponsored ads" tool for just that reason. It allows you to promote/feature any writing entry of your choice around the entire site, using your points.
We would like to possibly add new featured lists to the site in the future but we have to be careful not to feature too much. The point of featuring writing is so that it stands out, so if we feature all types (new, old, spotlight, not viewed, most viewed, etc...) it may interfere with its purpose.
It is certainly something to consider and we will look into what other types of writing we can feature.
Thank you for your feedback.
