Alas, I'm not active on any H/D communities at this time. You might consider looking at the profiles for legomymalfoy, february_sea, quiet_lucidity, mistful - H/Ders like that, and see what communities they belong to/watch. Perhaps that might help? Type Harry/Draco into "interests" and see which communities come up? Also post a link to your main journal page (just not the post itself) at FA's H/D thread?
