You will need to the faction plugin for bukkit once running then do in the chat
/f create {name of faction here}
Lava or make a hole and they "fall" through it
Impossible
To answer a faction invite just do /f join <faction name>
You use /f leave [faction name]
add them to your faction with /f join <faction name>
I assume you're talking about a faction invite. the command is /f join <faction>
If you are in a faction, and want to teleport to your faction home, just type /f home.
You have to build up your power (by adding more people), or have an admin do /f peaceful <faction name> and that will make your faction peaceful and make it so that nobody can hurt any member of you faction
/f claim and to set your faction home in that territory use /f sethome. For all basic faction commands type /f help (#1-9)
Press T
You kill mobs and players
