Fwy uses her own set of neos sometimes; in context when it makes sense among friendly folks.
So Fwy/fwyfwy/fwyself are all words you may occasionally see fwy use. Fwy doesn't make others use it though, we do appreciate it being used though; if someone addressing us can pickup the subtleties of it well enough to make the attempt. (Fwy promises it's not complicated)
Fwyself personally does use normal pronouns as well; such as She or singular They too; it helps confuse people less. Fwy sees no reason to throw up a barrier; only provide people subtle ways to signal intent or speaking context through either normal pronoun usage or fwyfwy neopronon usages; as that helps Fwy quickly route and allow the right entity to respond more quickly if they are used.
No one else in our System has ventured to publicise any neos yet besides fwyself; they simply don't seem to mind not having done so; particularly since using neos can get one singled out for harrassment fast in some internet communities.
