But it is ok to ask for fics that are around a particular time in a season, right, SMS? For example, "I'm looking for fics that take place/deal with Justin being a go-go boy." That might sorta come under the heading of gapfiller, but not necessarily. And, to me, that's a specific request, even if the searcher hasn't already read a fic about that topic and just can't remember what it was.

I do agree that "I'm looking for S2 fics" or similar is too vague.
