Well, good questions all around, Ann. I'll try to keep it simple -- I prefer copying the text into the body of the email, but if you send a file attachment I'll do the copying into the body of the anonymized email I'll forward to the DG myself (i.e. you'll be making more work for me, but I don't mind
); and ditto with leaving your name in the body of the email--whether it's there or in the email address line, I'll anonymize as necessary.
So, just submit away, and don't worry too much about what extras you leave in as I'll be doing the gatekeeper thingie, and excise anything extraneous before forwarding to the Host & DG.
Cheers,
...Alex
