This is interesting. I went back and looked at the emails t has sent me (weekly scheduling/payment emails and that is it) because I never really notice. She signs "warmly", or "take care" followed by her first name. Then her automatic sig follows with her full name, credentials, website and phone number. One time there was a disclamer attached but only once.

I sign with no closing, just my first initial. But my automatic sig (from work, where I usually contact her) has my full name, credentials and a huge long paragraph disclaimer. I wish I could get rid of it, but I can't.
