interesting. in the first example, i would have simply replied to all saying "it's not clear, but i am the original author of the proposal. please send your critiques to me as i own the document" or such. i don't believe in fighting deviousness with more deviousness. my days in the business world are obviously numbered.

as far as bcc goes i've never used it at work, but i do find it useful for social emails where i know a certain party is interested and can keep a secret. bcc is funny though, i use it so rarely that the bcc recipient can be confused. so i had to devise a certain code, a wording in the email that i wouldn't normally use, that certain people will recognize. i guess i can be devious in a harmless way. for being such a killer app email is horribly broken.
