Sphinx is issuing some warnings when I build the new docs:
```
reading sources... [100%] userguide/settings/plugins/youtube
/Users/gina/Sites/thinkup/docs/source/userguide/settings/plugins/youtube.rst:38: WARNING: Title underline too short.

Add a YouTube user to ThinkUp
---------------------------
checking consistency... /Users/gina/Sites/thinkup/docs/source/contribute/developers/plugins/buildinsight.rst:: WARNING: document isn't included in any toctree
/Users/gina/Sites/thinkup/docs/source/userguide/settings/plugins/youtube.rst:: WARNING: document isn't included in any toctree
done
```
Looks like we need to add the new docs to the correct indexes.
