I really like this plug-in since I was looking for a way to display the guest writers listed on a page.
I've managed to change most of it to what I really need.
I've deleted the alpha sorting and searching on last name, which I don't need. Also made some changes to the css file so it looks better on my template.
BUT, the thing I'm looking for is: How to sort the contributors on the amount of posts they have published.
The idea behind it is quite simple, put the number one poster on top, etc. and it will create a kind of competition between the writers (publishers), so they will add more content to be on top of the list.
Any suggestion ?
