crack_broom is a fanfic rec comm that rotates through different pairings. I don't think it's active on IJ (yet).
pervy_werewolf is Remus Lupin-centric, a bit more on the kinky side than some of the other Lupin groups. It seems to be a name-holder site for now, since the comm on LJ is still active.
Thanks for compiling this list, by the way. It's taken up most of my free time just to look around for mirror sites, so it's great that you've been so on top of keeping a mulifannish list with descriptions for each!
