In Have You Seen?, the point is to answer whether or not you have seen (or read, as the case may be,) whatever the person above you posted, and then bring up something you've seen/read/etcetera for the next person to answer.
Example:
It can be a movie or tv series, a book, a podcast, vine, or youtube video. Basically anything goes, so long as it's not, for example, a particular thing in your room or something else that nobody could have known about.
I'll go ahead and start: The Wood Nymph/Berries vines.
Example:
Person A wrote:The Lion King.
Person B wrote:Yes!
Guardians of Ga'hoole.
Person A wrote:Nope.
Welcome to Nightvale?
Person C wrote:Yeah.
(so on and so forth)
