Yep, it's still going on. We've currently got a Judges Guild subweb under construction (to be operated by Plaag), and I know he still needs a ton of scans. There's also a Planescape subweb to be unveiled before too long.
And of course, you can still make your own subweb, on any RPG-collecting-related topic that tickles your fancy. Submit your proposal to me, and we'll get you started.
