Depends on how you look at it I suppose.

You could say that `u:cam:simong` is a user resource at `/api/user/u:cam:simong` for which you update the `acceptedTC` property. That seems like a fairly RESTy way of doing it.

That said, I've added a `/api/user/u:cam:simong/termsAndConditions` endpoint that will set the accepted timestamp for that user.
