Civility is good; so is honesty and openness. Let's make sure we don't lose the one for the sake of the other.
While we wait for Mike Stangel's response on giving us another Suffix field for genealogy and DNA numbers, I think the managers & descendants of the profile have made it pretty clear that they want the SM/PROG put back into the Suffix field that we have at the moment, on this profile. I see that Judi has already done this, so this is just a heads-up to morel in reply to his query - that this is what we've chosen to do.
We hear you about the appearance in a project list being inconvenient, but it isn't very difficult for you to edit the name in wikitext, so it displays as you want it to on your project.
We also hear that you feel that you will then have the right to add 'Fille du Roy' into the Suffix as well as the SM/Prog. While I doubt that there will be strong objections to it, may I suggest that you need first to ask the managers of the profile if they will allow you to do that.
