heres my answers to your questions:
1:no idea bout the long saber. maybe it is a mod, but i have never seen it.
2:The bow thing sounds good to me. call me unmannerd, but I dont bow. I just take off at the other player.
3:binds: note: you must have cheats on. Bring up your console, and type in: "Bind x y." Where x=key, and y=cheat. to "make jestures" For y, put "taunt" (without the qoutations, of course.) Then just type that key and you do a taunt.
4:Everyone on the server sees the skin.
hope i was some help.
