I just finished a Transaction Manuscript, and one of the co-authors is a "Life member IEEE". Initially, I inserted "Senior Member IEEE" just after his name in the manuscript, but he pointed out to me that he is a life member. So my question is, can I remove the "Senior Member IEEE" and insert "Life Member IEEE" even though I haven't seen any paper having "Life member IEEE"?
Being a new graduate student, I never knew that you could add "life*" to the paper. I felt you can only add member, senior member, follow. After googling, for a while, I found out that one can add life member, life fellow, or life senior member to an author's name.
