I've been working on renovating User Settings, with the intention of pushing various settings out into other pages, making it less confusing to use each settings page, and making it a bit faster to load. It also has certain site-specific advantages due to the way the setting updates work.
SiteDocClan: please be on guard for documentation errors related to this change. Likewise please be aware that all of the settings nodes should now support sitedoclets which you can edit. Please feel free to add documentation to these pages.
