I was bugging OhNoesBunnies about making a Mandalorian character earlier and that seemed to be going well. You should poke him/her about it too, unless you think that's going overboard.
I've been pesting Silverphoenix and have told Vulpes he should make a Mandalorian, hopefully for Clan Rodarch, but besides that I don't know. Wit's new character Darman could join eventually if our IC interactions are played well, though for now Wit isn't looking at any place for Darman which is totally fine. Do you know anyone that's expressed interest in making a Mandalorian before? You've been here a bit longer than me.
