I have to agree on the "kill off" part.

... I mean, even if getting rid of a character seems like a [i]good[/i] idea, there's not such a high rate of fatal turnover that you could really explain 'and then this person is dead off-screen against nothing that they should be horribly threatened by'.

Plus people can be left without internet or what-have-you for some time, so removing them from the RP irrevocably seems a dick move.
