The Model Block will show a list of models in two columns, with a model icon besides each model.
If your site has a large amount of models and you dont want a huge list filling up your index of your site, you can use one of the alternate model widgets.
Two other Model Block Widgets are available.
Popular Models (being posts with most models) this list is sorted by count.
Popular Models and Sorted (this will also list the top models but it will by sorted in alphabetical order)
