i agree. send emails/chats whenever you want and it's up to the recipient to manage their notifications to prevent them from getting sucked in after hours.

- i'd rather log in at 9am and see a bunch of late night emails than logging in at 9am and then seeing a deluge of auto-sent messages flood my inbox at 9:01.

- there needs to be some 'core' working hours, but people may be in different time zones or may do their best work in different parts of the day. if you're a night owl, we shouldn't do anything to stop/discourage you from doing work at 1am.
