Dear Mun is now open for use at IJ!
It is actually the
brainchild of the wonderfully awesome
canadabear, who generously granted permission to use the name and concept at IJ.
Though I'm not involved in them, I have seen comms (some RP, some discussion) involving FMA, Red Dwarf, Spiderman, Batman, and Torchwood sprouting up over at IJ. :D
