There are a number of old Popeye posts here, just search on Popeye.
As for the other nicks, I have not seen them, but some may be posting elsewhere under new nicks.
Some are posting over at Stoogie's flame board. Most discussions over there range from flame threads, home cooking, conspiracy theories, sports, and a few music videos. They have a couple of hopelessly inarticulate liberals who post the most inane crap. You only rarely ever see an intelligent debate over there.
