I'm not completely sure about POGS at this point, but Kevin has mentioned a few times that everything that he's wanted POGS to process has already been processed, and we're just processing bonus data now (which in itself isn't a bad thing, in astrophysics more data is always a benefit). It seems likely to me that it'll be wrapping up sometime later this year.
As for theSkyNet in general, I'll probably still be performing basic maintenance on POGS, Sourcefinder, and theSkyNet.org while they're still up. I don't know if there's a plan to keep theSkyNet.org running after all the projects are eventually shut down, though. They might decide to shut down the website once both POGS and Sourcefinder have ended.
I also don't want this to be seen as a "thanks for the work, now goodbye" situation. I'm certainly going to be making the contributor's list webpage (which might replace sourcefinder.theskynet.org in the future) that lists all people who've contributed to this project, and is referenced in any publications that come about because of the work done here. I'd also like to do the same for POGS when that eventually shuts down, too. You've all contributed a lot of time and energy to both this project and POGS, and I don't want that to go unacknowledged.
