If you choose to email me using the email user function my rules are as follows:
I may not agree email is the appropriate place for the exchange, I will advise you on your talk page that I received the email and I think the conversation belongs on wiki.
If I do elect to have an email exchange with you then it is privileged and confidential, you do not have my permission to post it publicly without asking to do so.
Whether you follow my email rules is up to you but be aware I may refuse to engage in the use of email with you if you refuse to follow them.
