I use Links SQL to manage an article database. With the great program and effort from all here, I have added several function to every article:

related article;
rate the article;
put the article in my favorite;
recommend the article to my friends;
print the article;
talk with editor;
review the article;

Now I have some time to add more function to article. Do you have any good suggestion?

Take a look at the Sites In Action.
