I think a good addition to the Rules and Standards would be that when creating a new page without putting screen captures right away, the author should link to the source (video trailer, etc.) he/she is using as a reference for it.
This was brought to my attention on the
Splinter Cell wiki page for Splinter Cell: Conviction when one of the editors there pointed out that
our own page on the game doesn't have any mention of where the info is taken from.
So I propose that authors of new pages as such should have a link to the source (trailer, official website, etc.) that the list is built off posted somewhere on the page to verify its legitimacy.
