Jon E. Schoenfield: @Neil -- you mentioned that "it could have said A. M., email to ..., and then it would have been a kosher reference."

Does that mean that References-section entries with an underlined username that say "Email from" -- like the one in A175100 that just says

     Email from _David Applegate_, Oct 19 2010

-- are already kosher, and rather than moving them elsewhere, I should just passover them?  <g>

Jon E. Schoenfield: (... quietly and carefully carrying a sleeping dog back to where Neil said he had preferred it ...)  :-)

So ... is there any agreement as to whether the "Suggested by" and "Proposed by" entries I listed in the pink-box comment above (all of which occur in the References sections of their respective sequences), should be left in References with their underlining intact?

And, as Michel points out, there are a lot of suggested-bys in the Author field on other sequences.  Should those be left where they are, as well?

N. J. A. Sloane: It's a toss-up. I acually prefer it the way it was, because it could have said A. M., email to ..., and then it would have been a kosher reference.

Michel Marcus: Or author? where there are a lot of suggestion(s) ?

Jon E. Schoenfield: @Michel -- do you mean ... were there a lot of "suggested by" (or similar) entries in the References sections throughout the OEIS?  I found several:

Jon E. Schoenfield: References didn't seem like right field for this; moved it to Comments.  Is this okay?
