I've added SG:A Season 5 and the two SG-1 movies, Ark of Truth and Continuum, to the spoilers list.  Just a reminder, spoilers are required for the season currently airing in syndication (generally the season previous to the current Sci-Fi season) and all future seasons and/or productions. 

This is also required of any other fandom in the archive!

For books or other non-serialized fandoms, spoilers are required for the first year after publication/release.
