Purpose is of course identification of models, same lists as the ones opened from the websitelist should be fine, there are 3 options there
a list of sets from the website, (unusefull with this because no sets are defined)
a list of models with picture
and a list of names only.
I created such a list for paulmarkhamteens.com myself with the tags option

I understand it's very difficult to check and maintain the websites and names added by users. I asume there's a database behind it all so it should not be difficult to automate such a list, perhaps by an advanced search page.
