I play over at Tutis Tempus (http://tt-mod.dreamwidth.org/ for more info) - which is a cross of the HP universe moved into a Terra Nova-like world five million years in the past. We're a small, very friendly group with very easy activity checks (one post or journal/per month).
We have the potential to play dark lines (and adult). I'm open for plotty talk anytime. FYI, we'd love Fred&George and/or Bellatrix, lots.
