UPDATE: discovered that the System Settings do indeed contain settings for recaptcha. But they do not have a namespace associated in the Lexicon. Use the `search by key` to find them.
Makes me wonder: what other settings am I not seeing??
At any rate, I followed the instructions to a `T` here:
http://rtfm.modx.com/display/ADDON/Login.Login
I cleared my browser cache, the core\cache and reloaded the page in a browser that's not used to login to the Manager. I get the same old same old: it doesn't acknowledge my API keys; not my global nor multi-site keys.
Why? Because it simply doesn't save the keys. System Settings don't have a `Save` function the way Property Sets do.
So, instead of putting the values in `value`, I accessed the contextual menu and `Update Setting` to add the value there. I clicked on `Save`. AGAIN, it did not Save the values.
I noticed I got a squiggly underline error under
Namespaces when saving the Update Setting. So I selected `Update Setting` again and changed the Namespace to
login. I'm not sure if by doing this I'm associating/activating the keys only with login, or if it carries over system-wide for use in Quip.
