From a long time ago - Rue DeDay. Shirley Ujest. Eve, of course. Satan. Chief Scott. A lot of '99’ers.

Thanks, it’s always great to reread that thread.
It looks like Alice The Goon hasn’t posted since June of 2016.
He posts on FB regularly, making three or four posts a day. If you have a FB and don’t mind adding others, I can ask him if it’s okay to share his FB with you two, if you want.
Also on FB these days,
Also on FB these days.

I miss Inigo Montoya and Super Kapowzler. Quite the characters.
Mainly, I miss Sefton. He used to be so sane and composed, and now look at him.
I lurk more than I post, paid my subscription once upon a time and lapsed and lost my charter member status. Reading this roll call of names makes me sad in a way.
Most of the ones I miss are deceased and remembering makes me sad so we’ll skip that list. I miss the days when Tuba Diva was active as a poster and MOD. And I’ve missed Garden Traveler as well. I know both still lurk to some degree; I wish both posted more.
I miss Brutus. One of our more conservative posters, who had a working sense of humor. He left when we went pay-to-post. I emailed him shortly after, offering to pay for his membership, but he declined. I guess he was tired of the board.
DiosaBellissima. She was going to travel to Egypt again on vacation and then vanished.
Voyager - hasn’t posted since October.
Karl Gauss - hasn’t posted since September
Le Ministre de l’Au-délà - pops in occasionally, but work keeps him busy
Captain Ridley’s Shooting Party - hasn’t posted for a year or more.
Hypnogogic Jerk - left several years ago - I think because of comments in a heated thread about Canada and Quebec.
Michael63129 (I think I got the numbers right.) Used to post in GQ with some pretty good technical chops, then just up and disappeared.
Jurph.
He wrote the funniest post I’ve ever read on any internet forum (see “Let’s assign a “group roleplaying scenario” where the rest of the team can BLOW ME” (2006) if you can find it).
I’m not positive he is gone from SDMB, but I haven’t seen a post from him in a long time.
Here’s that post.
Jurph Hasn’t posted in 3 years.
Spice Weasel, without a doubt. She’s been off the boards for a couple months now and she used to be a prolific poster. Additionally, her Facebook page has been deleted. I’m seriously worried about her as she (probably unbeknownst to her) helped me through some of the most difficult times of my life and now seems to have no online presence.
Also, melodyharmonius. She was just plain awesome. She’s been gone for a couple years now I think.
Anaamika, naturally. I have her on Facebook and while she posts there infrequently I know all is well with her. Although I do miss her posting here—such a wonderful, intelligent person.
And I wish Marley would get his ban-happy ass back here and post once in a while. Someone said somewhere that he still posts in the mod loop, but a fat lot of good that does us. We need another nuking just to shake us up a bit and get us talking about something other than Trump.
+1 for many of the names you guys have mentioned. And of course I miss Skald the Rhymer—has anyone heard from him lately? And C K Dexter Haven, who was the Right Hand of the Master until he rode off into the sunset. And twickster. And ultrafilter. And (going way back) jarbabyj.
Not to mention all the beloved Dopers who have left, not just the Board, but this earth.
She hasn’t posted since January, but her profile says she was active just yesterday. Must be lurking.
Concur.
Charley Wayne and spamforbrains 
And Mean Old Lady…maybe the prettiest Doper. 
I’ve had better.
