Would like to see a system wide setting available to owner/admin that would set a "drop dead date" / auto delete period for all message on the system. Public channels, private groups & private messages. Owner/admin could set entire environment to auto delete in 7, 30, etc... days.

I believe chat should be ephemeral like real conversations. I believe therefore that logs of chat should have the option of simply going away if the owner/admin wants to promote that kind of environment.
