For my own information and because you will all need this information if I ever finish up a fic I'm working on...
SG-1 Season Ten, final episode: Sam, Daniel, Teal'c, Cam and Vala are still exploring the galaxy as SG-1.
Ark of Truth: ditto, one assumes.
SGA Season Four, Episode 3 'Reunion': When Sam leaves to take command of Atlantis, Teal'c is there to see her off and tells her that SG-1 will always be there for her, and agrees when she asks "So you guys will come see me?" To me that means Daniel, Teal'c, Cam and Vala are still exploring the galaxy as SG-1. ETA: in the episode before this, it's revealed that Sam's been promoted and is a full colonel.
SGA Season Four, Episode 17 'Midway': When Teal'c comes to Atlantis, he is wearing Jaffa robes, Sam introduces him as "Teal'c of the Jaffa" and she says that "He was a member of SG-1 for over ten years." That tells me Teal'c is no longer on SG-1, and we don't have information about Daniel, Cam or Vala.
SGA Season Five, Episode 1 'Search and Rescue, Part 2': at the end of the episode, Sam tells Rodney that she's going back to Earth because "SG-1" has been invited to witness the extraction of Ba'al from his host, and because she's having a performance review. When she reaches the SGC she finds out from Woolsey that she's being relieved of command.
Continuum: Jack, Sam, Daniel, Teal'c, Cam and Vala are all at the extraction, representing "SG-1", but we know that Jack, Sam and Teal'c are no longer on the team. We don't have information on the others (unless the other three are wearing SG-1 patches, while Jack, Sam and Teal'c are not. I'll have to research that, unless any of you know?) At the end of the movie, Sam hopes to discuss plans for the new moon base with Jack. ETA: Jack himself is wearing an SG-1 patch in Continuum, so we have no actual knowledge that any of them are still SG-1 team members based on their shoulder patches.
ETA: SGA Season Five, Episodes 10-11: How could I forget Daniel's trip to Atlantis to annoy Rodney find Janus's secret laboratory? He arrives wearing civilian clothes, and has obviously been doing a lot of research that has led him to suspect there is a secret lab right there on Atlantis. I'm going to say he's no longer on SG-1. Because I can. So there. At the end of the ep, in the Atlantis infirmary, Daniel says Landry wants him back on Earth to recuperate from his injuries. That bothered me for a few seconds, and then I realized that the order was passed along through Landry, but came from a different general altogether. *g*
SGA Season Five, Episode 20 'Enemy at the Gate': Sam is temporarily in command of the SGC while Landry's heading up a task force in Washington, and is scheduled to take command of the new and newly-renamed Hammond. ETA: She tells Sheppard that she was off-world when she heard about Hammond's death. Maybe on the moon base?
SGU, various: Sam is in command of the Hammond, Jack remains in command of Homeworld Security at the Pentagon, and based on Episode 1-17 'Subversion', Daniel is in Washington. Daniel is able to tail someone, at Jack's request, who is already on his way out of the Pentagon building. As far as I'm concerned, Daniel has the office right next door to Jack!
