Have a question about how the TVTropes wiki works? No one knows this community better than the people in it, so ask away! Ask the Tropers is the page you come to when you have a question burning in your brain and the support pages didn't help.

I honestly don't see the point of WMG pages for people, so it could probably be cut (especially if it's about him and not his work), but I'd imagine a Quotes page would be harmless as long as the contents don't get too personal. I haven't checked either page, but I feel that there's too much potential for WMG subpages for Creator pages (in general, not just this one) to attract gossip.
I got a rock for Halloween.I think most internet personalities with trope pages also have subpages, particularly ones like James Rolfe, etc.
The Protomen enhanced my life.YMMV.Allison Pregler and the like are also subpages, but also redirects from Obscurus Lupa. What should be done with those?

I saw the TearJerker.Doug Walker page had been recently edited. Since it's a Creator namespace, doesn't that mean they don't get subpages? Should they be cut?
