I'm a real novice on this so bear with me. 

Now when I send an email out, the recipient receives the message stating from "me"  my full name, first and last.  At times, I do not want my last name shown.  I can't figure out how to change it.  My profile  says my alias is my email address - which is fine.  But I do not want my full name shown as sender.  Can you help?     Claudia
