Woah there.
Hasty.
I have noticed nardi in the "Users browsing the forum" at the bottom on several occasions and he hasn't posted. So here's what I think.
If he is a Townie, he's going a pretty horrible job at "blending in." He stands out as a lurker and doesn't even attempt to post anything meaningful.
If he is a Mafia, he's trying to sabotage the game by the same cause so Mafia loses. That's Pretty Gay (tm).
I really doubt a Mafia would sabotage his buddy like that so I'm leaning toward the possibility of him being a Townie.
Yes, I'm defending nardi, but it's not like he's here so he can to defend himself anyway. =\
EDIT: [strike] and added "to" to make sentence more understandable.
