The key to getting reCaptcha to work with MODX Revo 2.2 (and lower?) is to put your public and private keys in the System Settings and change their Namespace from `recaptcha` to quip or login.
1) First, get your keys from your Google account. If for some reason you don't want a google account but still want keys, send me a PM with the domain(s) you want to use and I'll set up keys for you.
Get your keys!
http://www.google.com/recaptcha
2) Add the keys to your System Settings. How: use the `Search by key...` filter on the right. In this example I put `reca` and tapped `return` on my keyboard. (did you ever notice how violent it sounds when people write `hit return`? Me, too.)
3) Right click in the Setting name to access its contextual menu, and select `Update Setting`. Enter your key in the `Value` area, and then change the `Namespace` to
login or
quip. Save and close.
If you don't change the namespace, the value will not be saved.
I'll update this thread when I find out if the Namespace is just for whatever namespace you choose, or if it's valid system-wide, meaning you can choose the
login Namespace but also activate recaptcha to use with
Quip.
4) Follow the rest of the instructions here:

Recaptcha will now display! Yay for you!
