You're right of course. I do actually have one sequel on AFF, a seventh year Harry/Pansy sequel to a sixth year one and guess what, it's stalled and pretty dead when i got past Malfoy Manor.

Ha ha. Yeah, turning it to Harry/Draco is sure to get more readers. Or you could just have Draco appear in a couple of times, Exchange snark with Harry, and label it 'pre-slash'.
