Use of real name as an identifier is a necessity

This is a very good module but I think it should allow users the option of using their real names in the Make an Invitation page. When a user sends an invitation, the recipient may not recognize a person based on the username he uses with a website. If I send an invitation to a friend and the invitation says something like alpha123 has sent you an invitation to samplesite.com, my friend will not know who alpha123 is and take that invitation as spam and ignore it. However, if I’m given the option to type in my real name and my full name is on the invitation, my friend will take that invitation seriously and would be more compelled to accept my invitation. I hope to see this feature soon. Thank you very much.
