I'll locally fix up before queuing this time, but

 * You now have one in-body header to force "From: QueenJcloud",
   after which the blank line declares everything below is the body
   and no in-body header remains, and then you have another line
   "From: Queen Ediri Jessa" that is not an in-body header.  Perhaps
   you should send your e-mail only to yourself without sending to
   the list as practice to prevent them from appearing again?  You
   only want the second one, IIUC.

 * Describing "Changes since..." is a very good idea, but that
   should be done _after_ the three-dash line, not beffore.

Thanks.
