No - it's important that you NOT put your signature at the top of your
emails.
You probably want to do this because some legal beagle in your company
thinks you need an email disclaimer, and it has to be read before your
message. This is (almost) undiluted rubbish. Google for "email
disclaimers" and read all about *why* email disclaimers are basically
pointless, irritating junk.
