I've created a filter for RPG-design posts. Not just for posts concerning gaming, but the nuts and bolts of designing and thinking about games and settings. Mainly, it's going to be used to workshop stuff before it appears on the site. If you want to be in on it and enjoy thinking about mechanics or setting design, you should already be on. If you're logged in and can't see the post above, leave a comment. Likewise, if you're on the filter and don't want to be, say so.
